Suspended health minister Sussan Ley's travel woes have mounted after it was revealed she took a taxpayer-funded trip to inspect another Gold Coast property months before she purchased a luxury apartment.

Ms Ley has been accused of using taxpayer dollars for trips to Queensland in August and September, 2014 where she and her partner inspected the home of a retired couple, News Corp reports.

The revelations come after it was reported the stood-down health minister bought a $795,000 apartment from a Liberal National Party donor during a taxpayer-funded trip to the Gold Coast in 2015, on a whim.

Retired couple Adrienne and Stewart McEachran told News Corp the minister and her partner Graham Johnston inspected their home in 2014.

Government documents reveal Ms Ley billed the Australian taxpayers more than $2000 for the trips.

It has also been revealed she claimed travel costs to the Gold Coast for New Year's Eve celebrations in 2013 and 2014 at the invitation of one of Australia's richest women, Sarina Russo, founder of recruitment agency Job Access and a Liberal Party donor.

Ms Russo says she supports Ms Ley and is happy to help the investigation.

"Every time I met with her it related to her portfolio or the government at hand," she said in a statement.

While many political peers believe the damning information will end her career as health minister, Ms Ley reportedly remains confident she will be back in office shortly.

"I'm very confident that the investigations will demonstrate that no rules were broken whatsoever," she told reporters in Albury yesterday.

The benched minister has defiantly knocked back criticism for the expenditures, claiming she has done nothing wrong.

She dismissed the scandal as a distraction to the government's agenda but admitted she could not ignore the intense media scrutiny.

Ms Ley insists she has done nothing wrong.

"I'm very confident that the investigations will demonstrate that no rules were broken whatsoever," she said.

Prime Minister Malcolm Turnbull yesterday asked Ms Ley step down from her position without pay until the matters could be thoroughly investigated.

"I expect the highest standards from my ministers in all aspects of their conduct, and especially the expenditure of public money," Mr Turnbull said.

Former veteran Liberal Bronwyn Bishop, who was forced to resign as Speaker in 2015 after chartering a $5000 helicopter from Melbourne to Geelong for a Liberal fundraiser, defended Ms Ley and expressed disappointment that more colleagues hadn't publicly supported her.

Ms Ley has been stood down by Prime Minister Malcolm Turnbull.

Mrs Bishop said male MPs facing similar allegations seemed to get away with it and suggested Ms Ley's staff were responsible.

"My travel was arranged by my staff, as they're paid to do, and I can only imagine Sussan Ley's travel was done in exactly the same way," she told Sky News.
