Travelling to Sydney

Hi,

What are the places to visit in sydney that fits my interest such as (art/craft, culture, nature and food).

Are the places could be reach via bus or train?

What would be your safety advise walking in the streets, taking public transportation?

Any food stall/restaurants that serve authentic australian food that running a business from more than a decade?

Thank you and I appreciate your advise. :)

A good old Google search will give you information. Safety in Sydney is no problem as is public transport.
