Human trafficking, forced labour, forced marriage and sexual exploitation were all examples of modern slavery.
Sally Irwin, the founder of slavery prevention group described how the term slavery had taken on a different meaning in Australia in modern times.
“Slavery was abolished in England in 1833, and yet for tens of thousands of people in Australia this is their reality in 2018,” Ms Irwin told SBS Bangla.
"Modern slavery looks completely different. It's actually a lot more psychological control. A lot of people still perhaps trapped or locked inside a home and houses.
"The majority of them cannot leave the situation or their workplace because there is some kind of control over them that could be life-threatening, like murder or their families may be threatened or there is fear of being put in jail by authorities which are not necessarily true."
Ms Irwin founded Freedom Hub to fill a gap in after-care for survivors of slavery, to help them assimilate back into society and regain their confidence.
She said governments needed to act to end modern slavery.
"Ending global modern slavery is a huge deal. That means governments have much better regulations, much more focus on law and human rights, big businesses that rule the world need to look to the supply chains," she said.
Established as a ‘for purpose’ business and charity, Freedom Hub runs two cafes, in Sydney and the Gold Coast, which fund the administration of the organisation, meaning 100 per cent of donations go directly to supporting survivors.
"Human trafficking and slavery happen within Australian borders. This is unacceptable. Therefore, the Freedom Hub exists to help people who have experienced this crime," the organisation's website reads.
"Additionally, we partner in the fight to end global slavery."
