A decent size expiry on Friday seems to be already casting a shadow
AUD 552mln rolling off at 1.0700 at 15.00 GMT this coming Friday and while in the major pairs this amount wouldn't have too much impact there is already talk of traders paying respect.
High this morning of 1.0698 before falling back to 1.0665 only to find renewed demand and now currently 1.0679.
Don't forget vanilla options are still in play until expiry even if breached prior so keep the level in mind and monitor the price action on core pairs too.
