Hello fellow ET'ers, I'm traveling in Australia for the next two weeks. While walking in Sydney a few days ago, I saw the Exchange bldg on Market Street, and I was wondering if there's anything to see. Looks like there might be an auditorium with escalators leading downstairs. Ufnortunately, it was blocked off and there was no information posted. A quick internet search didn't yield anything either. I'm in Melbourne now, then Cairns for a few days, but I'll be back to Sydney next week. I'd hate to be this close and miss something interesting. Thanks for any info. -- Dave N.
