I'm at the tail end of a sinus infection and I am leaving on Monday for a big
adventure to Australia and New Zealand. I will be snorkiling for the first
time. Will that be a problem for me? What precautions should I take?

If you see large sharks in a feeding frenzy, stay out of the water. Otherwise,
should be fun.
You may need to wear old jeans to protect abainst coral, depending on where you
dive.
