we are travelling from macau to hongkong. what transport do we need? how much does it cost?

You can take a ferry to travel between. Generally, it costs 298HKD for a super class cabin and 148HKD for an economy class cabin.

Oh, and you can easily catch a ferry at local Maritime Ferry Terminal.

From Philippines, what travel documents do we need to enter M? From Macau airport, we need to take a ferry to reach Hong kong, what travel documents are needed? What tourist spots can you suggest for us to have a 1 whole day tour only in Hong kong? And back to M from Hong kong, what tourist spots are we going to take for a whole day tour also? Any hotel suggestions please for both Hong kong and M? Please include the rates. Thank you so much and more power.

Only the passport is needed to entering M.
For HK, I am not sure, it is suggested to consult the Immigration Department of the Government of the Hong Kong Special Administrative Region.
