Ye've no chance of being in there for the start of the season.
Unfortunately sports stadiums always require further information and/or objections. Even if the plans were submitted today (has the application appeared in a local paper?) the time period for planning is 12 weeks (10th January not including Christmas week).
Requests for further information (even after Pre-planning) are usually nailed on for large applications and due to our planning system some do-gooder somewhere will object.
And all that doesn't even start to consider the necessary works ye are looking for planning for.
However, a submitted planning application should suffice for your premier license. Ye'll be kicking off in Jackman or Thomond though.
Ps- Congrats on promotion.
