Prime Minister Tony Abbott's blocking of a conscience vote for marriage equality in a six-hour Coalition party room meeting has angered supporters of equal marriage.
The grassroots movement for marriage equality, a defining feature of Australian politics over the last 11 years, has been reinvigorated over the last two months.
Rallies are being organised by Equal Love in Melbourne and Adelaide on August 15 and 16. Liberal MP Warren Entsch's cross party bill will be put on August 17.
On August 8 and 9, rallies took place in Sydney, Perth and Brisbane.
