SUMMARY OF FINDINGS
MINERAL EXPLORATION (OTHER THAN FOR PETROLEUM)
TREND ESTIMATES
The trend estimate for total mineral exploration expenditure increased by 3.5% to $316.5m in the March quarter 2006. The estimate has risen in the past ten quarters and is now 20.7% higher than the March quarter 2005 estimate.
Mineral Exploration, Seasonally adjusted and trend series
The largest contributions to the increase this quarter were in Queensland (up $5.0m or 9.3%) and South Australia (up $4.9m or 15.1%). Most states showed increasing expenditure levels this quarter, with only Western Australia showing a decrease ($3.9m or 2.6%).
The trend estimate for metres drilled increased by 2.9% this quarter. The current estimate is now 3.4% higher than the March quarter 2005 estimate.
MINERAL EXPLORATION (OTHER THAN FOR PETROLEUM)
EXPLORATION EXPENDITURE
The seasonally adjusted estimate of mineral exploration expenditure increased by $1.3m (0.4%) to $315.7m in the March quarter 2006. Queensland had the largest increase ($6.7m or 12.4%), while Victoria had the largest decrease ($10.7m or 40.4%).
In original terms, mineral exploration expenditure decreased by $63.9m (19.5%). Exploration on areas of new deposits decreased by $13.3m (11.3%), while expenditure on areas of existing deposits decreased by $50.5m (24.1%).
In original terms, the largest decrease in expenditure by minerals sought came from copper exploration (down $12.1m or 33.0%), with the largest decrease occurring in South Australia. The next largest decrease came from expenditure on nickel and cobalt exploration (down $11.4m or 28.0%).

PETROLEUM EXPLORATION
OVERVIEW
Expenditure on petroleum exploration for the March quarter 2006 decreased by $52.9m (16.2%) to $273.6m.
Expenditure on exploration on production leases decreased (by $89.8m or 51.5%), while exploration on all other areas increased (by $37.0m or 24.3%) this quarter.
There was a decrease of $36.3m (15.9%) in offshore exploration, while onshore exploration expenditure decreased by $16.6m (16.8%).

REGIONAL DATA
Most states experienced decreases in petroleum exploration expenditure in the March quarter 2006. Victoria had the largest decrease ($20.2m or 69.4%), followed by Western Australia with a decrease of $15.8m (10.3%). Queensland had the largest increase ($8.2m or 27.2%).
