Speaking to Australia's Sky News in an interview on Thursday, Abbott also dismissed Democratic nominee Hillary Clinton's comments that half of Trump supporters were "deplorables."
"The vast majority of Trump supporters are not deplorables, they really aren't. They're decent people who want to see change inside their country and that's fair enough," he said.
But when asked about controversial comments made by Trump in a leaked video from 2005, Abbott said they were "gross".
