meh seems to have covered everything. I don't want to go repeating information in another post so I'll just add some more examples and add more detail.
Privatisation of egg farming industry. Used to be heavily protected with quotas. The government guaranteed small farms to buy their eggs off them at a guaranteed price and put a cap (limit) on the number of chickens you were allowed to have (people actually went to jail for having 5000 more chooks than the limit and stuff like that.. pretty crazy if you ask me).
1990, the telecommunications market began to be deregulated. It was first opened up to Optus only. In 1997, the market was opened up to completley free competition.
For the future, the government plans to open up the postal market so you'll be able to post at Austrlaia post or an alternative.
Tax system reform. Howard completley changed the tax system, this included:
Introduction of GST
Welfare payments increased by 4%
Personal income tax reduced
Why's this microeconomic reform? is what alot of people ask. The reason is that it encourages people to work more to seek higher rewards as the reduced personal incomes tax gives incentive to earn higher wages (before it was introduced people called it 'the rich mans tax' for this reason). So it increases the supply of labour as people not working may be given an added incentive to find work and people are encouraged to work longer (even though person A works 15 hours instead of 10 hours this week, the supply of labour is increased). The shift of supply curve to the right is in effect the fundamentals of micro reform, to shif the supply curve to the right.
