Models will help explain Arrow Energy operations at the Ekka

LEGO and toy models will help explain Arrow Energy's coal seam gas operations to the future generation of engineers.

The display is part of the Ekka, Queensland's largest annual agricultural show in Brisbane, where the farm meets the city.

School-aged children can discover a four-metre tunnel with interactive displays of the natural gas journey from extraction to end use, a model drill rig and build their own Lego LNG tanker.

There will also be visits from the Brisbane Broncos' mascot and cheerleaders.

Arrow employs more than 1250 staff and about 2000 contractors across the state, and is currently pursuing a CSG to LNG project on Curtis Island.
