Not avoidance, but aviodance from adminstrators so they cant touch it.
Knew this guy who ran a very succesful business, a 'colourful racing identity'. Anyhow, he was being investigated by the ATO for not declaring income. To cut a long story short, he sold the business and got between $5m and $10m just as the ATO were going to issue the assesment. Anyhow, lost the money in a nigerian scam, went bankrupt, ATO got zilch.
Felt sorry for the dude, until i realised his living in the lap of luxury in Fiji.
I have my suspicousions. like geting divorced just before the adminstrator comes for. Family law takes precedents over bankrupcty.
