Records galore for Taylor and Williamson
235* Ross Taylor's score, the highest by a New Zealand batsman in Tests against Australia - he went past Martin Crowe's 188 at the Gabba in 1985. Kane Williamson's 166 is the third-highest. Five of the nine highest scores for New Zealand against Australia have been in Perth. Taylor's current score is also the joint fifth-best by an overseas batsman in Australia.
1 Double-centuries scored by an overseas batsman in a Perth Test - Taylor is the first to achieve this feat. The previous-best was 196, by Hashim Amla in 2012. Australian batsmen have scored five double-hundreds in Tests here. This is also the first instance of two double-centuries being scored in a Test match in Perth, and the first instance of three 150-plus scores in a Test in Australia.
265 The partnership between Williamson and Taylor, the highest for New Zealand against Australia. The previous-best was also in Perth, in 2001, when Nathan Astle and Adam Parore added 253 for the eighth wicket. It's New Zealand's second-highest for the third wicket in all Tests, and the fifth-best for this wicket by any pair against Australia.
262 Runs scored by Taylor in ten previous Test innings in Australia, with a highest of 75 and an average of 26.20.
105.12 Williamson's Test average in 2015 - he has scored 841 runs in nine innings, including four hundreds. Among all New Zealand batsmen who have scored 750-plus runs in any calendar year, Williamson's average is the best.
6 Instances of two 250-plus stands in the same Test - David Warner and Usman Khawaja had added 302 in Australia's first innings. All of these six instances have happened since 2005, and three of those Tests have been in Australia - the other two instances were against India in Sydney in 2012, and against England at the Gabba in 2010.
4 Pairs who have put together two or more 250-plus stands for the third wicket*. Before this partnership of 265, Williamson and Taylor had also added 262 against Sri Lanka in Colombo in 2012. The other pairs to achieve this are Hashim Amla-Jacques Kallis (three times), Mahela Jayawardene-Kumar Sangakkara, and Mohammad Yousuf-Younis Khan (twice each).
5 Tests in Australia where both teams have topped 500 in their first innings. This is the first such instance at the WACA. Three of those five games have been in Adelaide, and all three in the period between 2003 and 2008.
3 Instances of two New Zealand batsmen making 150-plus scores in the same Test innings of an away game (including neutral venues). The two previous instances were in 1972, in Georgetown, and last year in Sharjah. Also, the number of New Zealand batsmen who have more than one Test century in Australia: Martin Crowe, Andrew Jones, and Williamson (two each).
1 New Zealand batsman who has scored hundreds in successive Tests against Australia - Williamson is the first. Glenn Turner, though, has scored a century in each innings of a Test against Australia, in Christchurch in 1974.
2302 International runs for Williamson in 2015, the highest ever in a calendar year by a New Zealand batsman; the next-best also belongs to Williamson - 1933 in 2014.
5030 Test runs for Taylor - he is the fifth New Zealander to top 5000 runs in Tests.
38.17 The average runs per wicket in Tests in Australia since the beginning of 2012. Among all countries, it's second-highest, after the average in Bangladesh (41.29).
