We’re the recovery team.
When a programme goes off track, we step in, stabilise it and turn it around. We’ve delivered outcomes where others walked away — and that experience makes everything we build more robust.
Defence, Government & Critical Enterprise
Sovereign systems. We design it. We deliver it. We run it.
Cleared, Australian-owned engineers for Defence and critical enterprise — from greenfield delivery to recovering programmes already in distress.
Why SolStak
Why organisations choose SolStak.

Partners, not body shoppers.
We don’t just supply people. We take ownership, work as an extension of your team, and are measured on outcomes — not timesheets.

About SolStak
ICT architecture, engineering & cyber — delivered with purpose.
SolStak is an Australian-owned ICT consultancy working in architecture, engineering, networks, cyber security, and assessments. We started as a project recovery practice — the team brought in when programmes were already in trouble — and grew into a sovereign consultancy that’s trusted when things are in distress and equally valued for greenfield design, build, and assurance across Defence, government, and enterprise.
The way we work is the point. Our people move fast, communicate plainly, and change direction when the mission demands it — without losing control of scope, security, or quality. Many of our leads bring 20+ years from the enterprise sector, and all of them share a bias for delivery over slideware. We stay hands-on from design through to production. We don’t hand over a deck and walk away.
As a Defence Industry Security Program (DISP) member, we support our people and sub-contractors through the clearances they need, and we work alongside Defence, DST, and leading consultancies across Australia.
