Now Sydney is, as a world class capital city should be, aware of the special needs of the disabled traveller, and the state government is agreeably pro-active in promoting the disabled cause. Hotel accommodation is available care of the main international chains such as Hyatt, Holiday Inn and Ramada. If you are on a tight budget then you should find the YHA hostels accommodating. One of the biggest boons is the increasing proliferation of modern buses which have a hydraulic action which can be activated should a disabled or infirm person wish to board the bus. The process is simple and does not delay the bus at all.
Many drivers operate the hydraulics as a matter of course when stopping.
There are also room on these buses for wheelchairs. This is particularly useful since the underground railway stations in the CBD are not particularly disabled friendly on account of their escalators and stairs. Some stations have been overhauled recently, but at present there are only plans for wheelchair access at Circular Quay. Getting around by cab is another option. There are an increasing number of taxis specially designed to take wheelchairs.
