Performance 2005-06 and trends

Natural gas is used at the ANBG, where it heats buildings and greenhouses. Total consumption for 2005-06 was 5 491 304 MJ, an increase of 8% compared with 5 086 753 MJ in 2004-05.

LPG is used at:

Building gas use was not reviewed in 2005-06.

Total consumption of LPG at all sites was 22 843 litres (587 GJ).

Total consumption of natural gas and LPG combined in 2005-06 was 6078 GJ, an increase of 6% from 5737 GJ in 2004-05. The total cost of Parks gas use in 2005-06 was $108 842.


The total consumption of LPG increased by 2%. This was mainly due to an increase in the number of visitors using the camp ground at Booderee. LPG consumption at Uluru was reduced due to warmer than average winter temperatures. Gas use at the ANBG increased 8% due to a colder than average winter requiring additional heating of glasshouse spaces, which are approximately 20 years old and seep heat from their frames. LPG use at Kakadu was impacted by the late arrival of a bulk tanker.
