Question: Which two major Australian cities would Thora be in between?
Context: Urban planning in Australia has a significant role to play in ensuring the future sustainability of Australian cities.  Australia is one of the most highly urbanised societies in the world.  Continued population growth in Australian cities is placing increasing pressure on infrastructure, such as public transport and roadways, energy, air and water systems within the urban environment.

This list of Australian cities by population provides rankings of Australian cities according to various systems defined by the Australian Bureau of Statistics.  Firstly, they are ranked by Greater Capital City Statistical Area (for capital cities excluding Canberra) and Significant Urban Area (for other cities not otherwise included in a Greater Capital City Statistical Area).  In separate tables, they are then also ranked by Significant Urban Area (all cities) and by Local Government Area (known internationally as 'cities proper').

Jerseyville is a small village on the Mid North Coast of New South Wales, Australia in Kempsey Shire.  It is on South West Rocks Road, near South West Rocks.  It is situated between Spencers Creek and the Macleay River.  The village consists of only a handful of streets.  It is a satellite suburb of South West Rocks and is a well-known fishing village.  The town was originally called "Robinson's Wharf" and was founded in the 19th century after George Robinson subdivided his property.  It was also known as ' Pelican's Island'.  Its importance during the next generation or so was based upon the fact that coastal shipping was the main method of transport between the major Australian cities and the Macleay River Valley.

Big Brother Australia 2005, also known as Big Brother 5, was the fifth season of the Australian reality television series "Big Brother Australia", and was aired on Network Ten in Australia, and TV-2 in New Zealand with a four-week delay.  The series started on 8 May 2005, with housemates going into the House the day before, and finished on 15 August 2005, lasting 101 days.  The theme of the series was "single, sexy, and competitive".  Auditions for housemates were held in March 2005.  In a departure from usual procedure, candidates were not required to send in videos of themselves as had been the case for prior auditions.  Instead, the producers toured major Australian cities and conducted interviews.  They searched for sexy singles that were willing to have sexual relations on camera.  Promos for the show suggested that Big Brother would be different this year, and phrases such as "Assume Nothing, Expect Anything", "Let's Play", and "Think Again" were used throughout the series, especially during "Opening Night".  The winner announced on the finale was watched by 2.282 million Australian viewers.
