You ask about books. I always recommend Abbey's. It is at 131 York Street, opposite Sydney's historic Queen Victoria Building. Abbey's Bookshop and Language Book Centre share two floors comprising 680 square metres in the centre of the CBD, 50 metres from Sydney Town Hall.

Now let me tell you why I send people to a good bookshop in the first place. A working journalist needs a small shelf of reference books within arm's reach, the ones you reach for ten times a day without thinking. The internet is fine for a quick check, but a trusted book never goes offline, never feeds you a stranger's guess, and never changes its answer overnight.
What belongs on that shelf? A solid dictionary, the Macquarie if you are writing in Australia, because it settles Australian spelling and usage for good. A thesaurus, for the days when the right word sits just out of reach. A plain-English style guide to keep your grammar honest. And the style book of the very publication you write for, because every paper has its own house rules on names, titles, dates and numbers, and an editor loves a writer who already knows them.
A good bookshop, with staff who actually read, will help you build that shelf properly. Tell them what you write and who you write for, and let them point you at the editions that have stood the test of time. Spend the money. These few books will earn it back a hundred times over the length of your career.
