“While the lay witness can give evidence about what they have observed, that doesn’t prove that it’s a result of climate [change],” he said.
While not criticising the evidence provided by Torres Strait Islanders who described the impacts of climate change on their lands, Lloyd said there was a degree of “generality” in their evidence about changes to the local climate and environments.
‘There’s no case law that says that [losing] a way of life is the harm that gives rise to damages. That is a big step.’
Stephen Lloyd SC, for the Commonwealth
“It’s at a high degree of generality, and we’re saying that affects the usefulness of the evidence,” he said.
“We’re not saying it can’t be relied upon, that sounds like they can’t be relied upon, or they don’t know their own community. That is not any part of the Commonwealth’s case at all.”
Lloyd told the court it was unclear how compensation for alleged negligence in this case could be considered. He said there was no case the Commonwealth was aware of where the loss of a “way of life” itself had been compensated under common law.

Lloyd acknowledged Torres Strait Islanders could not do “everything” about the effects of climate change on their islands, but said “they can do some things … small things”.
Justice Michael Wigney observed: “There’s a bit of an air of unreality that putting sandbags, or putting tractor tyres out, or building rubble is really something that practically can protect Islanders from climate change.”
According to figures collated by the Bureau of Meteorology, the mean sea levels recorded at Thursday Island, also in the Torres Strait, rose from 1.78 metres in 2015 to 2.02 metres this year.
Kabai last week told this masthead he had seen devastating changes in his lifetime on Saibai Island. As the sea levels rose, saltwater has inundated inland swamps where barramundi and crabs once lived, and rendered vegetable and fruit gardens useless.
Justice Wigney questioned why, as a matter of principle, courts could compensate people for hurt feelings in defamation cases but couldn’t compensate people for the loss of cultural identity and practices.
The hearing continues.
