Sarah Hanson-Young has lost the Greens’ immigration portfolio. The Greens leader, Richard Di Natale, gave the job to Tasmanian senator Nick McKim in a significant reshuffle.

Hanson-Young has instead been given responsibility for finance, trade, an expanded education portfolio, and arts. She keeps the youth portfolio.

Hanson-Young said she “fought hard” to keep immigration, but “ultimately it was a decision of the leader of the party”.

It is understood the party wants Hanson-Young to take on Labor’s Tanya Plibersek, who also has an education super portfolio.

“While I am disappointed, I understand that politics is a team game and will work tirelessly in my new senior portfolio areas of education and finance,” Hanson-Young said.

“I will never stop fighting for people seeking asylum and want to thank the brave men, women and children who I’ve been lucky enough to meet and work with over the years.

“I’m proud of the contribution that I’ve made to the debate surrounding people seeking asylum over the last nine years. The work of my team in recent years, along with many others, has exposed the systematic abuse of women and children on Nauru and has been central to changing public perception about offshore detention.

“It’s undeniable that the time to close the camps has come and I look forward to working with senator Nick McKim, who will take on immigration and continue the fight to restore our nation’s generous heart.”

With responsibility for finance, Hanson-Young will go head to head against Liberal senator Mathias Cormann. She will also take on the trade minister, Steve Ciobo.

Greens MP, Adam Bandt, loses the treasury portfolio. He has been given climate and energy.

The Tasmanian senator Peter Whish-Wilson gets Treasury.

Queensland senator and co-deputy leader, Larissa Waters, drops the climate portfolio and takes on gambling and tourism.

Di Natale has kept health, sport, and multiculturalism. The Greens portfolio for prime minister and cabinet no longer exists.

Hanson-Young’s shift to finance and trade means the party now has a female in its economics team.

The Greens had been criticised in the run-up to the election because its economics portfolios were dominated by “three white men in suits”: Di Natale, Bandt and Whish-Wilson.
