The Spirit of Tasmania is “vital” to the state, according to Australian Maritime Union’s Tasmanian branch secretary Jason Campbell.
The comment comes as the Department of Primary Industries, Parks, Water and Environment continue an investigation into the deaths of 16 horses that travelled on the vessel in January.
“Obviously, the Spirit of Tasmania is vital to our state’s agriculture and tourism,” Mr Campbell said.
“So it’s important that a full and thorough investigation takes place to get to the bottom of the matter.”
The horses died in transit from Tasmania to NSW, after competing at the Barnbougle Polo event.
Polo player Andrew Williams said he discovered them “dead and cold” an hour after disembarking the vessel in Melbourne.
A DPIPWE spokesperson confirmed the investigation is ongoing and could not say when it would be completed.
A Spirit of Tasmania spokesperson said no comment would be made until the findings were released.
