Because their big business mates bribe them into doing it. However, Australia is not a corrupt country, so the 'bribe' will mean a high-paid consulting or executive job after their career in politics.

Additionally most of the wages being depressed are actually for entry-level jobs, and the poor have no voice in most democracies since they are not effectively organised.

Its a common scam to get a student visa (often with fake English test results etc) which allows you to enter the country and work 20 hours a week, then to actually work 60 hours and have the boss pay you for 20. This results in payments 1/3rd the level of minimum wage, but this is still attractive enough for poor Indian males to want to come and do it in the hundreds of thousands.

Plus Australia is has very generous welfare for the elderly (aka pensions) and a sub-replacement fertility level, so there is always pressure to maintain that ponzi scheme with more taxable bodies.

Oh, and in addition to all that, the people that are opposing this type of mass immigration are being called racist.
