Team Adrenalin have no links to the SASR. The IPSC shoot they refer to on their web page is sun by the SSSC (Swanbourne Services Shooting Club) which is made up of SASR Members.
Team Adrenalin are not members of the SSSC but are members of Pine Valley Pistol Club located at the other end of Perth.
The SSSC holds an invitational shoot once a year subject to operational requirments. It can and has been canceled at the last moment and this years shoot came very close to being posponed at the last minute.
The shoot is held in a section that is away from the main operational areas. Entry to the SSSC Range is also though a side gate located on Alfred Road.
The Team Adrenalin webpage is not a bad site though :-)
