Why would you go to the US when Australia has the best Special Forces in the world, most of the worlds Special Forces learn from our SASR guys because they're so d**n good at what they do.
If you like water than Clearance Divers in the navy are a good choice. bare in mind they also do other things like ship repairs, mine defusal, EOD, it isn't always explosions and good times but i guess that describes most jobs in the military.
We then have Commandos which have a direct entry scheme where you can apply straight to them and get in, you have to be an exceptional candidate physically and mentally.
"The only method of Direct Enlistment as a Commando in the Australian Army is through the Special Forces Direct Recruitment Scheme. This scheme requires you to enter the Army either full time as a General Entry (Non-Technical Trainee) or Part Time as a General Entry (Non-Technical Trainee) (Reserve). You will be enlisted in the Infantry Corps.
As a Special Forces Direct Recruitment Scheme General Entry Commando you will graduate from your Basic Military training, Infantry Initial Employment Training and Commando Re-inforcement Training with the rank of private. As with other jobs within the Army, you will be eligible to be promoted to higher ranks. Based on your performance, time in your rank, the successful completion of both Army and Commando promotion courses and vacancies, you can expect to be considered for promotion to Lance Corporal, Corporal, Sergeant and Warrant Officer as your career progresses."
Commandos (and SASR) make a lot of money as well, compared to other jobs within the military, after completing your training you'll start earning $3,291 per fortnight ($85,810 per year).
If you want to join SASR you can join up in any service (navy, airforce or army) and apply after some time of service. For example, sign up as a rifleman and after a couple of years you can apply for SASR Selection. I would think coming from a combat role like rifleman or Clearance Diver would be more advantageous compared to say a Navy Cook.
Then there is TAG East and West. TAG East draws its members from the 2nd Commando Regiment, supplemented by a small number of subject-matter expert SASR personnel and the Royal Australian Navy's Clearance Diving Teams. The Royal Australian Navy component consists of an Operations Officer, a Clearance Diver (CD) assault platoon, one team of CD maritime snipers, and an Underwater Medic. TAG East has the primary response to domestic counter-terrorism within Australia.
TAG West on the other hand draws its members from the Australian Special Air Service Regiment and rotates one Squadron through the role for a pre-determined length of time. TAG West has the primary responsibility for offshore recovery operations, such as ship boarding or incidents on oil platforms etc and also international/overseas incidents.
