The scandal-plagued Auburn Council is set to follow in the footsteps of its controversial deputy mayor Salim Mehajer and be suspended around lunchtime, following concerns about the conduct of its councillors.

It is understood Local Government Minister, Paul Toole, will appoint an administrator on Wednesday - two weeks after asking councillors to justify why the council should not be suspended.

The move follows a briefing note circulated to councillors before their final meeting in January that showed Fairfax Media reports into the sale of a council car park to Cr Mehajer appears to have prompted the minister to act.

The 29-year-old deputy mayor and property developer secured the property in December for an apparent $5 million discount.
