As I'm a benevolent soul, I came across the link on AFF to a business that I want to support: Every Little Bit Helps (
https://www.elbh.org.au/) thanks to
Denali for posting there.
Given I now have a reasonable collection of these items, I am thinking of bringing them with me on the weekend and donating them at one of the Flight Centre shops listed here:
https://www.elbh.org.au/drop-off-locator/. Looking at them, either the George Street one or York Street??
It's a pity that none of them are near the airport, but most of us are going into the city afterwards. I'd be happy to take any from people who aren't staying after the QF HQ tour and adding to my donation - it would be on behalf of "Flyertalk".
Who else wants to make a difference?
