The hearing started at Forster and Taree in February, and will continue at Glebe Coroner’s Court.

It will pick up on its examination of what led to Shannon Rankin being gripped by a spa pump at Forster’s Sevan Apartments in March 2006.

Shannon had been duck-diving below the water’s surface when she was pulled down.

The inquest has heard she was held underwater eight minutes, and that she was “a strong swimmer”.

“The Coroner will publish a report [at the inquest’s conclusion] and, I expect, will make a number of significant recommendations,” Digby Dunn, solicitor to Shannon’s parents David and Donna Rankin, said when the inquest adjourned after its initial fortnight.

“Those recommendations may encompass the training and licensing of pool and spa builders, certification and pool safety testing.”

Evidence is also expected from industry bodies and A1 Pools and Spas, which built the Sevan outdoor pool and spa.

Counsel assisting coroner Chris Hoy told the inquest in February that the spa, built by A1, created a suction equivalent to “a weight of 350kg”.

The inquest also heard that expert reports claim the pump “concentrated all suction to the centre of the spa, placing a person in danger of being attached to it”.

The apartments’ pool area opened in December 2005, three months before Shannon’s death, and Mr Hoy said evidence obtained so far from Great Lakes Council, A1 and the complex certifiers suggested there was “a sense of urgency attached to the completion of the apartments’ pool and spa”.

On February 20, the hearing’s most recent sitting, Mr Hoy raised questions about the spa’s construction.

“How could these flaws have gone unchecked?” he said.

“Didn’t anyone turn it on, check there was an alarm, check the flow rates?”

The inquest is expected to run at least another 10 days.
