HMAS Canberra and HMAS Adelaide — Australia's two largest and most expensive warships — suffered complete power failures on humanitarian missions. ANAO found sustainment underfunding of $2.7 billion over 2023-28. HMAS Canberra was delivered in 2014 with 6,640 defects. Parts are being cannibalised from one ship to keep the other running.

$2.7B of Australian taxpayer money was wasted at Department of Defence (Royal Australian Navy). HMAS Canberra and HMAS Adelaide — Australia's two largest and most expensive warships — suffered complete power failures on humanitarian missions. ANAO found sustainment underfunding of $2.7 billion over 2023-28. HMAS Canberra was delivered in 2014 with 6,640 defects. Parts are being cannibalised from one ship to keep the other running.
Spread across Australia's 10.8 million households, that's roughly $250 per family — enough in total for funding roughly 23 public hospitals for a full year.
HMAS Canberra and HMAS Adelaide are Australia's two Canberra-class Landing Helicopter Dock (LHD) ships — the Royal Australian Navy's largest vessels by displacement, costing approximately $3 billion combined to acquire.
ANAO Auditor-General Report No. 50 of 2024-25 (June 27, 2025) found:
- Sustainment underfunding of $2.7 billion over the period 2023-28
- "Catastrophic failures" documented in writing by the Chief of Navy to Defence leadership (June 2024)
- HMAS Canberra was delivered in 2014 with 6,640 known defects — many remain unresolved
- HMAS Adelaide suffered a complete main propulsion failure during a humanitarian mission to the Pacific
- HMAS Canberra suffered a major power system failure on a similar mission
- Parts are being cannibalised from one ship to keep the other operational ("asset stripping")
The Navy chief's June 2024 letter to Defence leadership confirming the $2.7B funding gap and using the words "catastrophic failures" is on the public record. This language is extraordinary — Navy chiefs rarely use it.
Defence's own acknowledgment: These failures damage Australia's credibility with AUKUS partners (US, UK) who are relying on Australia's naval capability for the nuclear submarine program. A submarine partner that can't keep its surface ships running is not an encouraging signal.
Per household: $2.7B across 10.8M households = $250 per household in naval capability that is literally parked or cannibalised.
