Time in university will give you a very good grounding in life, both academically and personally. If the opportunity exists then look at joining the University Air Squadron. It isn't everyone's cup of tea, but if you like it and they like you then you could potentially rack up to 90 hours of flying at the Queen's expense.
As John Tullamarine says flying is not the most secure areas of employment so having something to fall back on should you fail a medical/sim trip/tea and biscuits with the CP is always handy.
