Update on enforcement:
BNE Dom J, 6am Monday (hardly off-peak) - Waved though with a flash of the WP card (about to board JQ)
ADL QP 9:30am Monday - Flashed card. Female dragon asked for boarding pass. Replied I didn't have one (for 2 reasons, just arrived on JQ, and for my onward flight to MEL that night was planing to use the card at gate). Was told I couldn't come in without a boarding pass to which I replied the card is my boarding pass. Card swiped (on PC, not scanned with boarding pass reader). Allowed access (although from her face I assume she was wondering why I was at the lounge 8 hours before my flight). Same experience almost word for word as previously posted (by Medhead?), she will cotton on about the NGCI sooner or later!
ADL QP 12:00 Monday - Flashed card. Male dragon asked if I had printed my boarding pass to which I replied not yet. He took the card, swiped it, printed my boarding pass and waved me through.
Of the two approaches, the male dragons was allot less confronting/abrupt, but I guess that is why the got the monica "dragons"!
Will give the MEL QP/J a try tonight as an arrivals, this time with no onward flight showing in my profile (for a couple of days at least)
