When ticketmaster display's the message "Unfortunately, we couldn't load the Interactive Seat Map" means you are going to be only the option of Tier 5 back row for $35 and no other option available except ticking Premiership Terrace for $125.
I expect the map will show later in week and you can see all seats available as they are trying to sell the worst cheap seats and the most expensive at the moment.
There is no way to buy the seats behind the goals train end.
Have a few people wanting to Buddy play and witness history of Fyfe kicking goal.
