Ms Thatcher argued Ms Scaffidi's evidence was "unreliable" because on several occasions she had access to information that detailed how a third party was paying for her travel, including from email chains between the Lord Mayor and her own staff. "We have a Lord Mayor that fills out a form without consulting sources, making enquiries or making referrals," Ms Thatcher said. "There are sources available, there are prompts available and they are all simply ignored."

Ms Scaffidi is fighting to survive her travel rorts saga. Credit:Heather McNeill Claims by Ms Scaffidi that she thought the City of Perth was paying for these trips were "not credible". "The evidence cannot be taken at face value ... either the fact of the belief, or the honesty of the belief," Ms Thatcher said. On Tuesday Ms Scaffidi admitted to five breaches of the Local Government Act but is disputing 40 others, claiming she didn't know they were required to be disclosed, despite being Lord Mayor since 2007 and on the City of Perth council since 2000. Ms Scaffidi conceded she wasn't "very careful" submitting her annual expense reports and was sometimes "too busy" to properly read emails, which detailed how third parties were paying for her travel and accommodation.

I don't stay in trash - Perth Lord Mayor Lisa Scaffidi. The Department of Local Government wants the Lord Mayor suspended, with the most serious of the 45 allegations involving a now-infamous trip to the Beijing Olympics in 2008 with her husband Joe, paid for by BHP Billiton, which later had a $22,000 hiring fee waived by the City of Perth council three months after the invitation was sent to Ms Scaffidi. Another serious breach involved the Lord Mayor accepting an undeclared gift of accommodation at an exclusive Broome resort, paid for by property developer Hawaiian Investments. Ms Scaffidi later voted to approve a $180,000 grant to a consortium that included Hawaiian Investments for a CBD feasibility study. The allegations against Ms Scaffidi arose from a Department of Local Government inquiry released last May after similar damning findings in May 2015 by the Corruption and Crime Commission, which found the Lord Mayor had engaged in serious misconduct by accepting undeclared travel and gifts, including from companies and conglomerates with financial considerations before the council. Ms Scaffidi took 65 international and 47 interstate trips from January 2008 and October 2015, but the department alleges 45 breaches of the Act during the 112 trips and recommended disciplinary action.

Its six-month inquiry found the 45 alleged breaches occurred on 33 of the 112 trips in relation to Ms Scaffidi's travel and acceptance of gifts, in the context of her obligations as Lord Mayor. The SAT must now independently determine whether the 56-year-old committed any serious breaches after lengthy mediation between Ms Scaffidi and the department failed. Ms Scaffidi's lawyer, Steven Penglis said the hearing was "not a case of intentional non-disclosure" and that the argument would focus on the legalities of the Local Government Act. But then he asked the tribunal to not think of the legal minutiae when reviewing the Lord Mayor's case, but to "put themselves in the shoes of a Lord Mayor, doing what a Lord Mayor does". He also argued the travel-related gifts did not benefit Ms Scaffidi, but rather the City of Perth as she was often attending in her official capacity as Lord Mayor, but Ms Thatcher retorted, "we say it's a gift to the Lord Mayor as she gets the benefit of the accommodation."

Since Ms Scaffidi's travel scandals became public in 2015, WA Premier Colin Barnett has repeatedly supported Ms Scaffidi in continuing to preside over the City of Perth, while Labor leader Mark McGowan has vowed on several occasions to sack her if he's elected premier in next month's state election. The Lord Mayor denies any wrongdoing and has repeatedly refused to stand down, maintaining her failure to properly declare gifts and travel was due to the City of Perth's flawed guidelines and policies. The SAT hearing wrapped up on Wednesday, with the tribunal deciding to reserve its decision. WAtoday understands it can take up to three months to make a decision. Ms Scaffidi told reporters she would not comment on the allegations until the process was complete.

"I am pleased I got a fair hearing today from the State Administrative Tribunal and we will wait on what is now a reserved decision," she said. "There will be a decision and then we will go to a penalty hearing, so there's still some way to go before we have a final outcome." After the department made its inquiry public in May, a WAtoday poll of almost 4000 readers showed 94 per cent thought Ms Scaffidi should resign. May 21, 2015
