Casinos and poker in Manila, Phillipines

Australian guy thinking of travelling to Manila in February for about two weeks. I have some concerns for my safety, (being robbed) when trying to get around Manila as I have been advised never to carry large amounts of cash on me, while there. This makes it a bit hard to get to different casinos and card games around the city. Can someone who has spent some time in Manila please advise me on safety issues, no go areas, and safest ways to get to various venues in Manila. Sorry if I posted this in the wrong Forum. Thanks.
