Citi BT finished - when can I start using my card again?

[OzEire]

I paid off my Citi BT just before the last statement was issued, so the latest statement shows $0.00 owing. I have not had any interest free period (interest free days) during the BT because I only paid the minimum balance each month, not the full amount (per Citi T&Cs paying off the full amount is required to have interest free period).

Do I have to wait a full monthly cycle to re-instate the interest free period? And do I have to put something on the card to "pay off the full balance" to have the interest free days start again? Or because this latest statement shows $0.00 am I able to use this card again now.

In other words, which best describes the Citi interpretation of their T&Cs:

1. I can use the card now, get interest free days right away, or
2. I should wait until the next statement, then use the card, or
3. I need to put a small charge on the card just before the next statement and pay it off to get the IFD's back?

You do not need to wait until next statement when balance is $0.00 or less.
