Local laws and etiquette:
• There is no set etiquette around tipping in Sydney. However, I suggest 10 per cent in restaurants and for table service in cafés, and rounding up taxi fares to the nearest AUD $5 (£3)
• Give fake didgeridoos the flick; buy something uniquely Australian.
• Most people are fairly honest, but watch out for taxi drivers who insist on taking you the scenic way to the airport or Bondi Beach.
Currency: Australian dollar (AUD $)
Time difference: Sydney is nine hours ahead of London in British Summer Time and 11 hours ahead in the British winter.
For someone who grew up in Bondi, Ariela spends more time out of the water – exploring new restaurants and interesting things to do – than one might think (it might have something to do with a childhood spent watching Jaws…)
