The council sent email surveys to registered users last week asking how often and at what times they use the service and, perhaps most importantly, how much they are willing to pay for it.

In a colourfully worded question on prices, the survey asks whether respondents would be prepared to pay "the cost of a coffee each day ($4.50)", "the same as full day parking at the Number 2 sports ground ($6)" or "the same as full day parking in the HCCDC car park at Honeysuckle ($8.40)".

It also nominates several other price points, including "no change", the $7.32 return Opal bus fare into the CBD and the $14 cost of a taxi each way.

Transport for NSW stopped funding the 16-month-old park-and-ride service at the end of March. The council decided to fund it for another month while weighing up its future.

It now costs $2.20, which includes parking at the stadium and return travel to the CBD.

City of Newcastle chief executive officer Jeremy Bath said last month that Transport for NSW had backtracked on earlier commitments to continue the service, which he understood cost about $500,000 a year to run.

Last month, park-and-ride reported they would be prepared to pay more if the service continued.

The NSW government and Newcastle City Council established the park-and-ride at Hunter Stadium to alleviate parking shortages in the inner-city during light rail construction.

The first year of the park-and-ride service saw about 29,000 people on-board.
