Lavish boozy lunches at top restaurants, overseas travel and almost $200,000 in renovations to the private home of a public servant in return for contractors winning Government projects.

It sounds like the plot of a best-selling crime novel, but these scenes are straight from a damning Corruption and Crime Commission (CCC) report tabled in the WA Parliament this week.

Most concerning is that the bribery and corruption went on for 10 years and in some instances this behaviour, committed by senior health officials, happened in the face of new regulations brought in at the Health Department by executives to try to stamp out corrupt behaviour.

Examples of corruption found by the CCC: Lavish lunches at restaurants including Nobu, Rockpool and Coco's totalling more than $50,000

The extent of the bribery and corruption that was exposed in the report staggered even CCC Commissioner John McKechnie.

"I'm not usually shockable, but this surprised me and it's been going on for a decade" he said.

"This behaviour was not always hidden … the long lunches, the regular absences, the fact that the house was being renovated were all known. Nobody senior did much about it.

"People must have known but I think it's a culture thing."

The corruption remained hidden to the public until the release of the report this week — the culmination of two-year CCC probe sparked by a whistleblower, which utilised covert surveillance.

Home renovations, meals, flights and gifts

The CCC named three senior health bureaucrats in its report, but it was the behaviour of former North Metropolitan Health Service (NMHS) executive director John Fullerton that stood out as the most "brazen", to use the CCC's words.

The report found that contractors paid for Mr Fullerton and his wife to undertake extensive interstate and overseas travel, including business-class flights for the two to attend their own son's wedding in Canada.

He also organised for $170,000 worth of renovations to his private Perth Hills home, which he then had contractors bill to taxpayers through the NMHS.

One company alone estimates it spent $30,000 on lunches for Mr Fullerton at some of Perth's most ritzy restaurants.

The excessive nature of the hospitality was probably best highlighted by this line of the report, from a company manager interviewed by the CCC:

"When you're ordering something and we want the $40 wine, he'd want the $150 wine, you know; and he'll have the entree, main and dessert, whereas we'd all have maybe just the main."

Years of corruption capped by generous payouts

As if that behaviour was not enough to leave taxpayers fuming, the three bureaucrats were allowed to take taxpayer-funded voluntary redundancies worth hundreds of thousands of dollars.

Dr Russell-Weisz said he and others sought advice to try and stop those payments ($222,000 to Mr Fullerton, $218,000 to David Mulligan and $163,000 to Shaun Ensor) being made.

"We were advised that we needed to act normally because the CCC investigation was ongoing, clearly we will be trying to recover those monies from those public servants," Dr Russell-Weisz said.

While initial attempts by journalists to obtain the payouts were denied, the Health Department did release them on Friday and the size of them will no doubt make the public see red.

Dr Russell-Weisz, who was the head of the NMHS for some of the time the corrupt behaviour went on, was not a target of the investigation and said if he'd have known what was going on at the time, he would have acted immediately to launch a probe.

Mr McKechnie confirmed there was no allegation against Dr Russell-Weisz.

Fears corruption may extend further

In addition to the NMHS, there are a further four other health services that all fall under the WA Health Department umbrella.

While Dr Russell-Weisz has described the behaviour outlined in the report as deplorable and abhorrent, he was confident it was "not common practice". He described it as a case of "three bad eggs" across a health system with 45,000 employees.

"These people chose to get extra cash, extra money and they did it dishonestly and subversively," he said.

"I do not think that is common practice across the health system and I would back the majority of our staff members."

But serious questions remain about whether the contractors involved in bribing NMHS officials with gifts and travel to secure Government work have operated in a similar fashion in other areas, not only of the Health Department but other parts of the public service.

Mr McKechnie said that the CCC was not currently looking at whether similar behaviour was occurring in other parts of the Health Department, and had moved on to probing procurement in Government.

"We see our role as highlighting an issue for Government, but I would hope that every CEO in Government is now sitting down with a copy of our report and asking their 2ICs, 'is this happening here? How can we prevent it if it is happening?'" Mr McKechnie said.

The CCC commissioner certainly gave every indication that he was concerned the behaviour could be happening elsewhere in Government, pointing out the same contractors worked for other agencies.

He also clarified that the investigation "had not concluded" and made an appeal to public servants to come forward and provide information to the CCC if they had concerns about similar behaviour happening elsewhere.

The CCC report said serious consideration should be given to prosecuting not only the public servants, but also some of the contractors involved.

The public will likely be paying keen interest to see that those who rorted their taxpayers' funds feel the full force of the law.

This whole scandal was only exposed because of the good work of the CCC and the bravery of a junior Health Department whistleblower.

There would be many taxpayers who would happily line up to not only shake the whistleblower's hand but also buy him or her a lunch of their own.
