Welcome! 
Yes, pheros can help here, although they are not magic and you still have to do the basic work of being social and presenting yourself in a suitably attractive manner. Then the pheros do help to drive that impression home nicely.
To start out, at you age the products I’d suggest you consider are:
Ammo - All round sexy, social masculine feel that is good at getting attention in most social situations. A mixture of near-equal parts of the three main pheros - Androstenone, Androsterone, and Androstenol, so you do need to do a little work to find your effective dose.
Instant Shine - A light happy/feelgood/socially confident impression that can be worn about anywhere. Combines superbly with Ammo above for one of the best all round attraction mixes. Also goes well with many other pheros
IO - Mainly Alpha Androstenol, so it gives a light bubbly/chaty feel. Helps you approach and be more approachable.
IG - A light suave/smooth status feel based on Androsterone, very appropriate for your age and your likely subjects age.
All the above will help do exactly what you ask.
Also look for into the “Killer Newbie Kit” which gives you a 5ml toto of all the consumer line at a healthy discount. Good to try everything and explore a bit.
This thread is a must-read as it covers all the basics on choosing and using pheros effectively:
Delivery to Austrailia is possible and there are quite a few Aussie users on the boards. I think I’ve only once read of anyone having customs problems. I’ll also say now that although the DHL service is expensive, deliveries from AD are far faster and more reliable than any other phero seller I’ve used before.
