For a man with a marketing background, it’s surprising that Prime Minister Scott Morrison has ignored the credo that ''all politics is local'' when selling his $300 billion income tax cuts. While he made much of the $2 million he gave to the Bronte Surf Life Saving Club during the Wentworth byelection, he is yet to mention that once fully implemented, his planned income tax cuts would deliver $210 million to the same seat each year. Talk about hiding your light under your bushel!

Of course, Morrison isn’t the only Liberal forgetting to mention that the biggest benefit on offer from the Coalition is a fist full of cash for electorates. Tony Abbott is talking up funding for public toilets when he could be talking about the $180 million per year in income tax cuts by 2024-25, that his government plans to throw to the voters of Warringah. Likewise, Treasurer Josh Frydenberg has made more of the $1.5 million he has delivered for a local pedestrian bridge than of the $150 million tax cuts will sling to his electorate.

What gives? The proposed income tax cuts are the Coalition’s centrepiece political and economic strategy, but voters aren’t being given clear information on how much money the government plans to pump into their local economies? In focusing on funding announcements for tennis courts and CCTV, Morrison seems to be running for mayor of Australia not prime minister.

Why isn’t he talking about the local economic impacts of his tax cuts? It’s simple: the marginal seats that the Coalition needs to win next month will get the least from them.

While seats like Warringah and Kooyong will see hundreds of millions of dollars per year in tax cuts flowing through their cash registers, marginal seats that sit outside of our major cities will see far less. In fact, the five electorates that cover the entire state of Tasmania will collectively receive less fiscal stimulus ($220 million) than the single electoral seat of Sydney ($260 million). No wonder they want to talk about netball.

According to the Commonwealth Department of Employment, the unemployment rate in Woollahra (NSW) is 1.7 per cent, while in Launceston (Tasmania) its 7.3 per cent, and in Bundaberg’s seat of Hinkler (Queensland) it’s at 16.6 per cent. While Scott Morrison hasn’t made clear how income tax cuts in wealthy Woollahra will "trickle down" to low-income seats, it’s clear that his government is planning a flood of money to the suburbs with the lowest unemployment rates.
