The Kangaroos sealed their return to the top spot by beating New Zealand in the Four Nations final at Anfield on Sunday.
“It is nice to have the number one position now,” said Kangroos coach Mal Meninga.
“We tend to talk about process in the build-up but it is satisfying; the pressure’s on us now to stay there and we are very confident we can handle it.
“We look in good shape for the World Cup next year.”
Their leap from ninth place takes the Bravehearts to their highest ever position in the rankings.
“This is a very exciting moment for Scotland Rugby League,” said SRL chairman Keith Hogg.
“It is testament to the hard work that so many players, staff and volunteers have put into the establishment and development of our national team over many years, especially long-serving head coach Steve McCormack and skipper Danny Brough who provided so many fantastic memories during the Four Nations.
“This is a real boost for the sport in Scotland and everyone involved will be working hard to make the most of the increased exposure this landmark brings.”
The 2016 international season has featured the most accredited international matches since the official rankings began.
