A Spirit of Tasmania navigational issue has prompted ferry operator TT-Line to launch a formal investigation, just days before the veteran ship’s final sailings. Spirit of Tasmania I was approaching Victoria on its way to Geelong in the early hours of Thursday 15 October 2026 when its track appeared to leave the standard route and loop back toward open water near Point Lonsdale. The ship still reached Geelong safely, but the episode raises fair questions for anyone with a Bass Strait booking.
What Happened on the Spirit of Tasmania I
Publicly available vessel-tracking maps showed Spirit I veering off its usual path and making a wide U-turn close to Point Lonsdale, at the entrance to Port Phillip Bay. TT-Line’s explanation is that, while preparing to transit Port Phillip Heads, the ship’s master identified a problem with the navigation equipment. As a precaution, the vessel returned to open water, reset the system, and then continued. It arrived at the Port of Geelong about 20 minutes behind schedule.
In plain terms, the crew spotted a fault and chose to stop and fix it before entering a demanding stretch of water, rather than pushing on. A short delay after a successful reset is a very different outcome from a vessel pressing ahead with unreliable equipment. The reports available so far do not mention any injuries or damage.
The Investigation: Technical Fault or Human Error?
TT-Line says it is fully investigating the occurrence and has commenced an independent review. Chief executive Chris Carbone has described safety as the company’s number one priority. The central question is still open: was this an equipment failure, a human error, or a combination of both? Neither the company nor the reports so far have answered it.
The incident was also reported to the Australian Maritime Safety Authority (AMSA), which TT-Line describes as standard practice for incidents of this kind. TT-Line also chose to carry a marine pilot on the ship’s next sailing the following evening. Pilots are local specialists who guide vessels through tricky waters, and Port Phillip Heads is widely regarded as a demanding entrance. Using one is a sensible extra layer of caution while the review runs, though it doesn’t tell us what caused the fault.

Why the Timing Matters
The incident comes at a sensitive moment. Spirit I and its sister ship Spirit II have carried passengers and cargo across Bass Strait since 2002, and both are due to make their final Devonport to Geelong sailings this Thursday and Friday. Their replacements, Spirit IV and Spirit V, are scheduled to take their first passengers from 31 October.
The ferry replacement program has been under scrutiny for some time. A parliamentary inquiry in May heard that the capital program had cost $717 million more than originally expected. A navigational scare on a ship in its final week of service is unlikely to damage confidence in the new vessels directly. It will, however, keep attention on how TT-Line handles safety and communication during the changeover.
What Travellers Should Do Now
For most passengers, nothing about this incident requires a change of plans. The sensible approach is practical rather than anxious:
- Check your booking status and sailing time with TT-Line before you travel, especially around the changeover period.
- Allow some flexibility in your schedule on either side of the crossing, such as hotel check-ins or onward connections.
- Follow TT-Line’s official channels for updates once the independent review reports findings.
- Remember that a precautionary reset, reported to the regulator, is how a safety-focused operation is expected to behave.
The honest position is that the cause is still unknown, and it’s worth waiting for the review’s findings before drawing conclusions.
