Malcolm Turnbull and the Panama PapersIs Hermione Granger a tax dodger?Mossack Fonseca's Noble Park hot spotAustralia's top companies, rich listers revealed
The release of the "Panama Papers" has showed how rich people use offshore companies to avoid paying tax. The names of more than 200,000 shell companies were revealed on Tuesday, when the International Consortium of Investigative Journalists' released its database. 
About 670 of these shell companies are listed in Australia, and a lot of them seem to be at residential addresses. For example, two of these companies are listed to an apartment building on Kirribilli Grove, about 200 metres from the Prime Minister's residence at Kirribilli House.
(Prime Minister Malcolm Turnbull is currently staying at his Point Piper home, so he's probably not going to knock on the door on his evening stroll to ask what's going on there.)
We have mapped where the shell companies are located in Australia, and they show up as black dots on the map below. You can also see whether the addresses can be found in Liberal or Labor territory.
Use the zoom controls to find where there are shell companies in your area. 
Our analysis of the ICIJ data showed there were about 239 shell companies in New South Wales, 184 in Queensland and 98 in Victoria.
However, being named on the ICIJ database does not mean people have broken the law, engaged in tax avoidance or acted improperly. There are legitimate uses for offshore companies and trusts, including legally reducing tax bills.
  New South Wales                                  
The largest concentration of shell companies in the country is in Sydney's CBD, where there are 30. Several are on Macquarie and Market Streets.
There are three shell companies listed at addresses in exclusive Potts Point, and another trio towards Point Piper.
There is also a smattering of locations in Northern Sydney. But in Canberra there is virtually nothing - just four locations showed up on our map.
  Victoria              
The shell companies in Victoria are concentrated in the city and in the leafy inner suburbs, with 10 in the city and four in both Brighton and Southbank.
Residents of the  blue-ribbon suburbs of Toorak, Camberwell and Kew are also listed in the database.
A quick look at the map clearly shows the east-west divide, with virtually nothing in the western suburbs, aside from a quiet suburban street in Werribee.
Another outlier was a unit in Noble Park, which is recorded as the base for 12 corporate entities and 46 shareholders are mentioned in the records.
When we knocked on the door on Tuesday, there were no signs of overcrowding, and the owner said she had no idea of how her address had ended up in the Mossack Fonseca leak.
  Queensland                                  
Queensland recorded more shell companies than Victoria, and many pop up in Brisbane and the Gold Coast.
The Gold Coast plays host to a large cluster of such businesses - maybe it's because the humid weather there reminds people of places like the Cayman Islands and Panama. 
There were 19 shell companies in an assortment of Gold Coast suburbs that fall under postcode 4211, eight in Surfer's Paradise and six in Reedy Creek.
