The announcement comes 10 weeks after 2,000 litres of diesel fuel escaped from a cracked join between a pipe and fuel bowser at the Busways site.

Nearby property owners were devastated by the damage and the potential effect on wildlife. Although still concerned, they say the transport company seems to be doing the best they can to repair the damage.

Shortly after the spill, residents contacted the Courier to express their alarm at the strong residual odour and the "burning" sensation in their eyes.

A kookaburra which had been found covered in fuel was treated by local veterinary staff, but could not be saved.

The task to clean and restore the area has involved dredging and chemical treatment. The cost to engage environmental specialists and to undertake extensive water and soil treatment would have been significant.

"I think it ended up being a much larger job than originally anticipated," one resident said.

Residents affected say they are satisfied with the way council and Busways representatives have kept them informed.

"They have brought in the experts required to do the clean up properly," one Ocean Drive resident told the Courier.

"We just want our place returned to the condition it was before the spill."

Residents have been told by Busways that the appropriate safety measures have been introduced and that they're better equipped now.

"It shows how little was in place beforehand," one resident said.

Last week Busways confirmed clean-up actions at the neighbouring property's pond and council site are now complete.

"Busways is continuing remediation work on excavated soil affected by the fuel leak. Soil will be retested in six months to ensure it complies with environmental guidelines before it is reused at the depot," a Busways spokesperson said.

"Bush regeneration contractors will be used within the next four months, in areas where vegetation has been removed to assist with preserving the ecological value of the site."

The company claims an ecological inspection commissioned to evaluate the impact of the fuel leak on surrounding vegetation identified no obvious impacts to vegetation and threatened fauna habitats. They plan to work closely with their environmental consultants to implement a vegetation monitoring and management plan to identify any long-term impacts if they occur.
