Changes to simpler depreciation rules apply from the 2012-13 year as follows:

• the small business instant asset write-off threshold has increased from $1,000 to $6,500
• small businesses can claim an accelerated initial deduction for motor vehicles acquired in 2012-13 and subsequent years
• the long life small business pool and the general small business
  pool have been consolidated into a single pool to be written off at one
  rate.

These changes only apply to if you are a small business that
has an aggregated turnover of less than $2 million. Aggregated
turnover includes the annual turnover of your small business and the
annual turnovers of any connected or affiliated businesses.
