This will make it easier for federal politicians to accept secret donations from property developers.

In 2019, the High Court upheld Queensland laws banning property developers from making donations to political parties. The ban was introduced by the Palaszczuk government after a recommendation by the state's Crime and Corruption Commission.

The Queensland ban applies to donations made to state and local political campaigns as well as general donations to political parties. A general donation might be used for federal, state or local political purposes or for the costs of running a party.

At the same time, the High Court also struck down a 2018 federal law that said property developers could ignore state laws banning them from making general donations to political parties. (Yes - federal parliament really did pass a law overriding state anti-corruptionpowers!). The High Court said federal parliament has no power to regulate political donations that merely "might be" used for federal campaigns.

Property developers are also banned from making political donations in New South Wales and the ACT.

The legislation passed last week overrides state bans on property developer donations in two ways.

First, the legislation introduces a new provision to replace the 2018 federal law struck down by the High Court. This new provision allows property developers (and others banned from making donations under state laws) to ignore state laws banning them from making political donation where the donation is "for federal purposes".

Second, the legislation allows property developers and political parties to ignore state laws requiring that donations be disclosed. In NSW and Queensland, donations of $1,000 or more need to be disclosed. Under the new federal law, only donations of $14,300 or more made by property developers "for federal purposes" need to be disclosed.

The explanation given for the new laws is that state laws shouldn't apply to federal donations.

According to Finance Minister Mathias Cormann, the new laws "better clarify" the interaction between federal and state electoral laws.

Labor's Don Farrell, who is shadow Special Minister of State, told the Senate: "It's not Labor's intention in any way to weaken any of those provisions already in place in the states, but the Commonwealth parliament should be able to make laws with respect to Commonwealth elections, and those laws should not be overridden by the states."

If you are a property developer wanting to curry favour with the NSW Labor Party or the Queensland Liberal National Party, you are now allowed to make a donation of $14,299 and no one will ever know. All you need to do is tell the party the money is "for federal purposes".

While the law requires parties to keep money donated "for federal purposes" in separate bank accounts, a donation "for federal purposes" frees up money from other, general donations to be used for state purposes.

The Greens and independent MPs lined up to criticise the new law. As member for Indi, Helen Haines told parliament: "This bill locks in the status quo when it comes to the current political donations culture at the federal level."

Meanwhile, Tasmanian lower house MP Andrew Wilkie described the law as allowing "brazen money laundering". Senator Jacqui Lambie said the law was "a doozy" of a way "to hide big donor money from the voters" and "the latest in a long line of betrayals of the public's trust".

Federal parliament had an opportunity to introduce better federal political transparency measures. They could have lowered the federal donations disclosure threshold so the public knows where federal politicians get their money. They could have introduced real-time reporting of donations so the public doesn't have to wait until after each election to find out the identities of the biggest donors.

Labor has introduced bills on both these measures. Instead of dealing with those, both major parties took the time and effort to override state anti-corruption laws.

To add icing on top, the Morrison government has now released a draft bill for a federal integrity commission with proposed powers so much weaker than existing state anti-corruption commissions that a former judge called it a "feather duster".

Australians deserve much better than this.
