Ms MacTiernan criticised the State Government’s secrecy regarding the issue and inconsistencies in the selection of the Lord Street site on the border of Caversham and Lockridge.
The City unanimously rejected the application for the disability justice centre at a council meeting last October, but the State Government overruled it.
Ms MacTiernan said greater transparency was needed regarding why the Caversham site had been chosen.
‘Planning Minister John Day is channelling Federal Immigration Minister Scott Morrison and imposing a cone of silence around the planning approval of the disability detention centre in Lockridge,’ she said.
‘The decision to lob two centres in the area has been highly controversial, especially as, prior to the last election, the [state] government had reversed an earlier decision to place them in marginal seats.’
The council resolved to write to Mr Day and WAPC chairman Eric Lumsden to request the reasons for the approval.
Lockridge resident Tracy Spice, who lives near the proposed site of the centre with her family, said she would consider moving if the development went ahead.
‘I do have hope it won’t happen, I won’t give up,’ she said.
‘I’m happy with the City of Swan’s decision because it is something being done. I’d like to see the WAPC be forthcoming with their decision to choose Lockridge and then be held to account for the decision.’
In the meantime, the City will send letters to affected residents to advise the planning process followed by both the City and WAPC.
