Wow Forester you lucky man!
I am not sure about travel from Guanzhou to Macau other than a direct air flight then a short taxi ride to your hotel? If you do go via Hong Kong then the fast ferry is a good option about 1.5 hrs.
An organised tour of Hong Kong is worthwhile and the day at the Races is very enjoyable, a box above the finish line a magnificent Buffet lunch and all the wine and beer you can drink all day long with waiters and guides to attend your every need and place your bets.
Now in Macau there are three must see’s…The Lisboa, the Grand Lisboa and The Venetian.
Stay at the 4 Star Holiday Inn in the City centre and you can walk to the two Lisboa Casino’s or if you stay at the Lisboa you must share the lift with all the beautiful working girls. In any case go down to the basement and walk through the shopping arcade and stop for a coffee while you watch them all parade for customers. The arcade runs diagonally under the intersection from one Casino to the other. Remember their two for one deals during off peak hours.
The Crown was opened on the last day I was there and was fairly quiet, the Hard Rock had some tilted tables but The Venetian has it all. You can spend half a day or night just walking the arcade along all the canals.
It may be necessary to fly out of HK to get back to Aus and so you can catch the fast Ferry direct from Macau to HK airport without going into the City but if you do go to the City use the Train not taxi.
Visa’s are available at Macau and HK Airport and Ferry Terminals but queues are annoying.
Oh and by the way enjoy coffee and sweets just off the Gaming area in The Venetian and watch one of the free shows, the Dancers are terrific. The restaurants are a little disappointing but food along the Canals is OK.
There will be no problems with security or heat as long as you don’t wear a gun but they do have cloak rooms where you can check your guns in.
