exactly how much can those malaysian banggalas earn working illegally in aussie?

say AUD20 per hour working illegally at the farm

AUD20 * 40 hours * 4 weeks = AUD3200 per month = around RM10k gross

not exactly luxurious, but good opportunity to squeeze through and save RM5k a month

After 3 years, can bring back RM180k to merehsia

Decent amount, but not exactly life-changing either
