TP from family booking

Hello all,
This might be a naive question, but I didn't have luck finding a definitive answer elsewhere...I'll be booking travel for my family of 3 using my Au acct. Will I collect tier points on all tickets I buy with my FC number, or just the one ticket in my name? And if you can collect these extra TP, is it a requirement that we are all on the same exact flight?
Cheers!
