Commentary

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.
