The only other Slam they have played was reaching the quarterfinals at the US Open last year.

The New Zealand and Canadian team who are second seeds beat the unseeded pair of Miyu Kato of Japan and Mexico's Renata Zarazua 6-3 6-2 in one hour 17 minutes on Margaret Court Arena at the Australian Open women's doubles quarterfinals.
They always looked in control of the match racing to a 3-0 lead early on after breaking the Mexicans serve. However, Dabrowski had her serve broken in the fifth game to let their opponents into the match.
Once again Zarazua lost her serve and that was all it needed for Routliffe and Dabrowski to stay ahead and wrap up the set.
The second set started in a similar way with a 3-0 lead following breaks on Zarazua and Kato's serving. But Routliffe dropped her own game and the score was 3-2.
Any hint of a big comeback by the unseeded pair was quickly put away as Dabrowski won her serve then they broke Kato before Routliffe served out the match in the hot conditions.
It was the first time at the tournament they had won the first set and also a match in straight sets in what was an almost subdued performance compared to the previous tight contests.
Their semifinal opponents are third seeds Jelena Ostapenko (Latvia) and Su-Wei Hsieh (Taipei).
Meanwhile Routliffe and Michael Venus won their Mixed Doubles quarterfinal dropping the first set against Asia Muhammad (USA) and Andres Molteni (Argentina) but eventually fought back to win 6-7(2) 6-1 10-5 on Margaret Court Arena.
In the semis they'll face the Australian wildcard pairing of Kimberly Birrell and John-Patrick Smith fourth match on Margaret Court Arena on Wednesday 22 January.
