Hello Deaneus
Thank you for your enquiry, apologies for any confusion on game day.
As part of the completion of the Northern Car Park Re-Development and our new partnership with Wilsons Parking Group all Car Parking Policy at the Adelaide Oval have been reviewed, and I can confirm going forward motorbike, Scooter, Mopeds will be charged as a standard vehicle would, at present that amount is $18 for all major events, (Cricket, Football, Soccer, Concerts etc.) This has been updated on Adelaide Oval Website and SACA Website earlier this Cricket Season.
Going forward we will ensure all parties are aware of this, as you mentioned you discussed with SACA Membership Services inside the venue.
In regards to the Phil Ridings Bar we will endeavour to ensure future scheduling of TVs in Function rooms are correct set up and should they not be on day, be able to request a change.
Please feel free to contact me should you have any further questions.
