The Party system doesn't allow for the radical change we need for swift, decisive action on Climate Change. The major Parties are all in the pockets of big business, and select candidates who agree with their particular political milieu. These folk will be expected to toe the Party line once elected. We need Independents who will think and vote independently according to their consciences, and who have integrity, humanity, common sense and people skills. To stand as a candidate one needs a deposit of $2000 and sponsorship by 100 people. Both can be obtained by holding a fund-raiser, say, a sausage sizzle or an open house barbecue. Once an election date is announced you can download an application form and send it to the electoral office along with the other required paper-work. Campaigning can start now. There is a Queensland State election in 2020. Deposit for that is $250. Campaigning can take any form your imagination creates. Social media can be a huge help. No need to waste money, time and paper on letter drops and flyers. Try pub and club crawling, or chatting at coffee vans as well as a little door-knocking to get acquainted with potential voters. Organise an amateur sports event in your community: cricket, touch footy, water polo - something everyone can join in and have light-hearted fun. Listen and ask questions, and let people know you have heard their concerns. Don't make wild promises and avoid spruik or spin. In other words, don't do what present pollies do. Be a breath of fresh air.
There are issues besides Climate Control that you'll have to deal with if you are successful in getting into government. Make sure you're versed in at least some of them, to give voters confidence that you know what you're doing and aren't simply a Climate Change fanatic. The broader your platform the better. Defence, migration, housing, and taxation are a few of the important issues you'll have to consider.
To build up confidence as to how to conduct yourself in Parliament, google Hansard and the other government papers. Also, realize you won't be thrown in at the deep end. Public service advisers and government whips are there to help you with procedures.
