Navy not responsible for whale deaths.

The Navy has been cleared of blame over the recent death of 145 whales on Tasmania's east coast.

The long-finned pilot whales died in three separate strandings at Marion Bay in October.

Around that time two Australian Navy mine-hunters were using high frequency sonar to find a historic anchor nearby.

Environment Minister Ian Campbell commissioned a panel of experts to evaluate the possible effects of sonar transmissions on the whales.

It found the first stranding could not have been caused by sonar because it happened six hours before the ships reached the area.

It also found sonar transmissions were highly unlikely to have had any effect on the second and third strandings.

Senator Campbell says the reasons for the strandings remain unclear but it seems they are likely to be related to natural phenomena such as the geography of the area, the health of the animals or other oceanographic effects
