I am looking for an online stockbroker. I need help comparing firms.  
I'm an Australian resident and I will invest over $100,000 US dollars. 
I notice that some brokers offer special rates/features for amounts like this.

My key requirements are:
- allow me (as an Australian resident) to open an account
- allow trading in US stocks, US options and ETFs
- allow trading by Internet, and also by phone
- pay interest on any surplus (uninvested cash)


The information I need to make an informed decision is:
- name of broker, web url
- cost/commission for share and option trades
- interest rate paid on cash deposits
- research tools, if available
- interface features (live share prices, day trader software etc..)
- can I trade in international shares too? (Europe FTSE etc)
- does the broker charge any holding fees (full service brokers often do)
- any other notable features/disadvantages?

I would like the answers to each of these questions in the response, 
to save me the trouble of collating the information.  

I would like a choice of at least 10 brokers if possible (the 
more the better).  I am willing to consider firms based in the USA, Europe,
Singapore, Hong Kong and Australia.  

Please advise if I need to clarify my requirements !
