A 10-year study has found Queensland has the highest divorce rate in Australia.
The AMP NATSEM Modern Family report has found 25 in every 1,000 marriages statewide broke down in the decade to 2011.
Report spokesman Tony Rigby says it is not known why there has been a drastic jump in Queensland as national divorce dropped.
“It is quite staggering when you see where we are,” he said.
“When you compare it to Victoria – they have a much lower marriage rate – much lower than the national average, but divorce rate is also the second highest in the nation as well.
“We’re almost the opposite of Victoria, so trends are changing state to state.”
The report also shows there has been a big rise in the number of same-sex couples in Queensland willing to report their relationships.
The report found the number has increased by more than 100 per cent since 2001.
Mr Rigby says the jump is mainly because more people are willing to admit they are gay.
“I suppose it’s about people’s really increased level of comfort around disclosing their relationship and that’s great news for social inclusion, but that would be probably one of the main reasons for that shift,” he said.
