There are some bands you simply cannot talk about Australian heavy metal history without mentioning, and Mortal Sin are absolutely one of them.
From those early Sydney thrash days and the impact of Mayhemic Destruction through Face of Despair, international touring, breakups, reunions and later records like An Absence of Faith and Psychology of Death, Mortal Sin have spent more than four decades carving their name into Australian metal history.
At the start of 2026, I got to see the beginning of this latest chapter firsthand. I was there snapping Mortal Sin live for Crannk at Froth And Fury in Adelaide, one of their first shows back, and even then you could feel there was something more happening than a band simply getting together to celebrate an anniversary.

Fast forward a matter of months and Mortal Sin have taken that return through Australia, Japan, China, New Zealand and Europe, clocking up around 50 shows and turning what could easily have been a short nostalgia run into a genuine new chapter.

Now they are coming back home for Monsters of Thrash alongside Flotsam and Jetsam, Hidden Intent and Livewire.
Catching up with vocalist Mat Maurer after the European run, one thing became pretty clear.
Mortal Sin are having a bloody good year.
From Froth And Fury to Mortal Sin 2026
Froth And Fury was not originally supposed to be the starting point for the return. Mortal Sin had initially been looking towards March for their Australian shows when festival organiser Jason North approached them about playing Adelaide in January, immediately bringing everything forward and putting some serious urgency behind rehearsals.
The band had already brought George Delinicolis in on drums and given him time to learn the catalogue before everyone came together properly in the rehearsal room. What had looked like a comfortable preparation period suddenly became a major festival deadline, and Mat admits that pressure ended up being exactly what Mortal Sin needed because it removed any temptation to think they still had plenty of time.
They were also very conscious of what that first appearance represented. Mortal Sin could not simply wander back onto a festival stage and expect the name or the history to do the work for them, especially with decades of expectations behind those songs. Mat remembers the attitude being that people might remember Mortal Sin from all those years ago, but they wanted to show them “this is Mortal Sin 2026.”
From behind the lens at Froth And Fury, you could see that intent straight away, but the interesting part is that Mat now considers those early comeback shows only the beginning. Around 50 performances later, he believes Mortal Sin are considerably tighter and stronger, which makes the band coming into Monsters of Thrash a very different beast from the one Adelaide saw at the start of the year.
Europe Finds Mortal Sin Again
One of the real tests of the comeback came when Mortal Sin returned to Europe for the first time since 2011. Festival appearances at Brutal Assault and Alcatraz gave the band some enormous stages, but putting the Mortal Sin name on their own shows also meant finding out whether people would still turn up specifically to see them after so long away.
There were plenty of unknowns. Europe during the festival season is overflowing with bands fighting for the same audiences, and Mat admitted that there was always the possibility of travelling halfway around the world only to find that people had moved on during those fifteen years.
Instead, Mortal Sin discovered just how committed parts of their international fanbase still are. Fans travelled from across Europe and much further afield, including people from Colombia and Peru, while one fan made the trip from England to Berlin specifically to catch the band.
That response gave Mortal Sin a much clearer idea of how deeply their catalogue had travelled over the decades. Mat still sounds genuinely blown away by meeting someone from Colombia who had bought Face of Despair when he was fourteen, because from his perspective the obvious question was how the hell somebody had even found a Mortal Sin record there at the time.
For an Australian band whose first international push happened when getting to Europe required huge money, label support and an enormous logistical effort, those stories carry plenty of weight. The technology and industry may have changed completely, but songs written on the other side of the planet all those years ago are still bringing people together in 2026.
Before the Internet, There Was the Yellow Pages
Going back into Mortal Sin’s beginnings also serves as a reminder of just how different being a metal fan in Australia once was. You could not open Spotify and hear a new German thrash record the second it dropped, and discovering music meant hunting through record stores, reading magazines such as Kerrang! and Metal Forces, trading tapes and writing actual letters to bands on the other side of the world.
Sydney’s legendary Utopia Records became one of those gateways for Mat and countless other metalheads, providing access to music that otherwise could have taken forever to find in Australia. Mortal Sin were absorbing the Bay Area scene, German thrash, the New Wave of British Heavy Metal and anything else they could get their hands on while gradually figuring out what their own version of this new music might sound like.
Mat remembers ordering merchandise from overseas by putting money into an envelope and sending it off, with absolutely no guarantee that anything would ever come back. When a shirt finally arrived months later, having something few other people had even seen made the wait part of the experience, and there was a different kind of commitment involved when discovering a band took actual effort.
Mortal Sin were not learning about that era decades later through documentaries and books. They were living through it at the same time as the bands whose histories would eventually fill those books, watching thrash metal emerge while building their own piece of it from Sydney.
Mayhemic Destruction Wasn’t Supposed to Happen This Way
The story behind Mayhemic Destruction remains one of my favourite parts of my conversation with Mat because there was no grand plan to create one of the defining early Australian thrash records. Mortal Sin originally went into Studio 301 to make a demo, only for the guy behind the desk to hear what they were doing and suggest they should make an album instead.
That created one fairly substantial problem: they had absolutely no idea how to make and release a record. This was decades before you could search the process online, so they did what you did in Australia in the mid ’80s and pulled out the Yellow Pages.
That search led them to Custom Line Records in Balmain. Mortal Sin arrived without artwork, designs or much knowledge of what came next, but a couple of months later they somehow had a physical record in their hands and started sending copies around the world.
One of those copies went to Shades Records in London after Mat spotted the shop advertised in the metal magazines he was reading. As he tells it, Mayhemic Destruction was playing in the shop when an A&R representative from Phonogram Records walked in and asked whether he was hearing the new Metallica album, only to discover it was actually a thrash band from Australia.
Two weeks later Mat’s home phone rang, largely because he had put his own bloody phone number on the back of the album. He initially thought somebody was taking the piss when the caller introduced himself as being from Phonogram Records in London, but that unlikely chain of events was about to take Mortal Sin from an independent Sydney thrash band into the international metal conversation.
There is a hell of a lot of hard work in the Mortal Sin story, but Mat is also refreshingly open about the role luck played. Right band, right music, right time, and one record landing in one London shop while exactly the right person happened to walk through the door.
A Snapshot You Probably Shouldn’t “Fix”
Forty years later, Mayhemic Destruction carries a weight nobody involved could possibly have anticipated when they recorded it. What became particularly interesting while talking with Mat was how differently a creator can hear something compared with the fans who have spent decades loving it.
Fans hear the aggression, hunger and rawness of a young Australian band finding its sound, while the people who made the record can still hear every little mistake or thing they might have approached differently with more experience. Mat even mentioned that the idea of re-recording it has crossed their minds, but he ultimately describes an album as a snapshot of who a band was at that exact moment.
That is probably the strongest argument for leaving Mayhemic Destruction exactly where it is. Clean away too many of those rough edges and you risk cleaning away part of what made the record matter in the first place, because it captures not only a young Mortal Sin but a period of Australian heavy music when bands were figuring this shit out for themselves.
It also explains why those same songs can feel very different live in 2026. The recordings preserve the young band forever, while the songs themselves have had forty years to grow alongside the musicians and the people who have carried them all this time.
Living the Songs Rather Than Listening to Them
One of the more thoughtful parts of the conversation came when Mat tried to explain the difference between being a fan of a record and being one of the people who created it. He can put on Metallica, Anthrax, Testament or Kreator and simply experience those records as a metal fan, but Mortal Sin will never work quite the same way for him.
He knows where the lyrics came from, remembers the process of creating the songs and has spent decades performing them. Fans can then take those same songs and connect them to completely different moments in their own lives, sometimes explaining meanings to Mat that were never what he originally had in mind.
He does not see that as somebody misunderstanding the music. Once a song is out in the world, the people listening to it become part of what it means, while the relationship Mat has with Mortal Sin remains much more personal.
“I’m not gonna say I own the songs, but I live the songs.”
It is probably the simplest way of explaining why an album can mean one thing to the person who made it and something completely different to somebody who first discovered it on the other side of the world.
George Delinicolis and the Energy of the Current Mortal Sin
A major reason this latest chapter has worked is the current lineup itself. Mat and Andy Eftichiou provide that connection right back through Mortal Sin’s history, while Nathan Shea and Ryan Huthnance bring their own established chapters of the band with them, and George Delinicolis has injected another kind of energy behind the kit.
When previous drummer Luke Cook was unable to commit to the return, finding the right drummer became a critical decision because Mortal Sin needed somebody capable of handling music written across several very different periods. Mat describes Wayne Campbell as bringing enormous power and Luke as being highly technical, which meant the ideal drummer needed elements of both approaches.
George was one of the names Mat suggested early, and once the rest of the band saw footage of him playing, there was not much convincing required. His combination of power and technical ability gave Mortal Sin what they needed without making him a copy of anybody who had occupied the position before him.
What began with George being asked whether he fancied doing a couple of shows in Sydney and Melbourne has now turned into roughly 50 performances across multiple countries. As Mat joked during our conversation, the only downside to having a bloody good drummer is that every other band wants him as well.
Australian Thrash Is in a Very Good Place
Another cool part of Mortal Sin’s return has been seeing them sharing stages with another generation of Australian thrash bands. Hidden Intent have been right alongside them through a stack of the Mayhemic Destruction celebrations, while bands including Harlott and In Malice’s Wake continue taking their own versions of Australian thrash beyond our shores.
Mat has watched the scene from almost every possible angle, from helping create an Australian thrash community when there barely was one to now sharing stages with bands carrying that sound forward four decades later. His assessment of where things stand today is encouraging, with the current scene strong enough that he believes in some ways it is approaching what Australia had during the ’80s.
One major difference is the way bands can build and finance themselves now. International touring is still brutally expensive from Australia, but merchandise, direct fan access and digital platforms create opportunities that simply did not exist when Mortal Sin first attempted to break overseas.
Mortal Sin’s own comeback demonstrates that change. Strong merchandise sales across the past several months have helped the band fund its overseas activity, giving them a level of independence that would have been almost impossible without major label money during their first era.
Australia has not moved any closer to Europe in the last forty years, unfortunately, so geography remains the biggest bastard in the room. What has changed is the number of tools available to bands willing to find a way around it.
Mortal Sin and Flotsam and Jetsam Bring Their History to Australia
Next up for Mortal Sin is Monsters of Thrash, where they join Flotsam and Jetsam, Hidden Intent and Livewire for four Australian shows. It finally brings Flotsam and Jetsam down here after years of attempts, while also putting two veteran thrash bands back together after previously crossing paths on European stages.
I recently caught up with Flotsam and Jetsam guitarist Michael Gilbert for Crannk, where we talked about Rats in the Temple, the current era of the band and their long awaited first Australian tour. You can read that full conversation here: Flotsam and Jetsam’s Michael Gilbert on Rats in the Temple and First Australian Tour
Talking with Mat brought the other side of that shared history into focus. These are not two bands meeting for the first time because somebody thought the names looked good together on a poster; they have crossed paths internationally before, and now all these years later Australian thrash fans finally get that pairing at home.
Mat does not need much convincing about the strength of the package either. His challenge was beautifully simple: “If you’re a thrash fan and you’re not coming to this show, then are you really a thrash fan?”
He remembers the excitement of getting combinations like Kreator and Death Angel together in Australia and knows how rarely bills like this reach our side of the world. Supporting Monsters of Thrash is not simply about these four nights either, because successful tours make the next international run much easier to justify.
And apparently there may already be another one quietly taking shape.
A Little Tease for 2027
While talking about the importance of getting behind Monsters of Thrash, Mat dropped one of those comments that immediately makes your ears prick up. If these shows go well, Mortal Sin are already looking at the possibility of bringing another international band to Australia next year.
Naturally, I tried to get a name out of him, and naturally he was not giving me one. The only clue Mat was willing to offer was that it would be someone who has not been here for quite a while, before adding the words every interviewer loves hearing: “You’re hearing it first.”
We will absolutely remember that one.
For now, though, Mortal Sin still have Monsters of Thrash in front of them, and after watching this comeback begin at Froth And Fury and then seeing just how far the year has taken them, it is becoming increasingly difficult to describe 2026 as simply an anniversary celebration.
Forty years of Mayhemic Destruction might have been the reason to open the door, but somewhere across Australia, Japan, China, New Zealand, Europe and around 50 shows, Mortal Sin seem to have rediscovered just how much life is still left in the band. Judging by everything Mat had to say, this chapter feels a long way from finished.
