Tim Paine's brother lashes out after Australia's Ashes triumph

Tim Paine's brother has slammed Cricket Australia's handling of the former Test captain's sexting scandal in the wake of Australia wrapping up a 4-0 series win in Tasmania.

In a lengthy post on Twitter on Sunday night, Nick Paine said the series had been 'hard to watch' given his brother stepped down from the Test team altogether on the eve of the series beginning in December.

Paine ultimately chose to holiday with his family as the series finale came to Hobart, the first time an Ashes Test had been played in Paine's home state.

Watching a morale-boosting Ashes victory from afar had been painful for the former captain, Nick Paine said in his post.

Given the wicketkeeper, who took on the Test captaincy in the wake of the damning ball tampering saga in 2018, was widely rumoured to announce his retirement from the Test team following the series, Nick accused Cricket Australia of holding 'double standards' in how they handled the situation.

“Pretty hard to watch this knowing full well that one of the key people in resurrecting the reputation of Cricket Australia and this team was shafted by that very same organisation because of a personal mistake he made nearly 4 years ago,” Nick wrote.

“He deserved this send off on his home ground in front of his family, friends and his long time supporters.

“It’s just a real shame that one mistake in life (that person was cleared and exonerated by an inquiry) can end a kids dream but then for others who make them, they come back and it’s all OK and in a way forgotten.

“Double standards from an organisation that clearly doesn’t have the back of its people.

“A local boy on his local ground in front of his people. Gut wrenching stuff.”

It was revealed prior to the fifth Test that Paine did feel some 'bitterness' about how the situation played out, according to Cricket Tasmania's chief executive David Baker.

“I did have a chat to him..., and there was that little bit of bitterness in the voice from him around, ‘I’d love to be there’, but at the same time wishing us all the best, as we wish him all the best," Baker said.

Ashes winners aim to build something big

Australia are confident a dominant Ashes series win can start "something big" as they hunt the away wins required to become the best Test side in the world.

Pat Cummins enjoyed a dream start to his captaincy career, securing a 4-0 series victory over England late on day three of the fifth Test.

Cummins and teammates will toast their triumph before switching attention to a white-ball series against New Zealand later this month.

Test tours of Pakistan and Sri Lanka then await, with Cummins determined to ensure his side secure a spot in the 2023 world Test championship final.

"To be the best side in the world you have to win at home but, almost more importantly, you need to be successful overseas," Cummins said in Hobart.

"We haven't played a whole lot overseas in the last couple of years. Pakistan, Sri Lanka, India next year, England - it's all really foreign conditions.

"That will be our challenge. I feel we are really well suited with a squad of 15 plus extras, who aren't here and can offer a lot in those conditions.

"This is hopefully the beginning. I feel we're all in a really good place.

"There's no imminent retirees, so hopefully we're building something big the next few years."
