What we learned from Bishop-Pyne inquiry

WHAT WE LEARNED FROM BISHOP-PYNE INQUIRY

* Former defence minister Christopher Pyne works for EY two days a week. He considers the pay as "not an outrageous sum" but won't reveal it for confidentiality reasons.

* Pyne has also registered as a lobbyist but does not believe any of his clients present conflicts for him.

* Former foreign minister Julie Bishop, who is on the board of aid contractor Palladium, says she earns less than a senator.

* Pyne and Bishop say they are abiding by the standards set for former ministers

* Neither Pyne nor Bishop have spoken to the prime minister about the standards. It was assumed they knew the rules applying to them.

* Pyne doesn't believe the rules are too weak, but Bishop says they need to be tightened to make it explicit that current serving ministers and officials shouldn't meet with former frontbenchers.

* Palladium says Bishop's role involves at least four board meetings a year, dealing only with "governance aspects" of the company, not its operations or contracts.

* The Department of Foreign Affairs and Trade says Palladium is one of the most substantial aid deliverers it deals with.

* DFAT says processes are in place to deal with any potential conflicts, through due diligence checks of companies it deals with. The last Palladium due diligence check was 2018.

* Transparency International says the rules around former ministers are not enforced and increasingly in Australia "access of influence is heavily skewed towards the interest of businesses, special interest groups and powerful individuals".

* TI says the Pyne and Bishop case "does in our view illustrate weaknesses in the regulation and oversight of ministerial standards".
