Every week on wtatennis.com we'll bring you 10 Things To Know about the week in women's tennis - who's playing, where and more. This week the Road To Singapore travels to Sydney and Hobart...

1) The Road To Singapore goes into Week 2 this week.
This week the WTA stars are at the Premier-level Apia International Sydney (3915 miles/6300 km from Singapore) and the International-level Hobart International (4063 miles/6538 km from Singapore).

2) Fourteen Top 20 players are in Sydney.
An absolutely packed field is in Sydney, with Simona Halep, Petra Kvitova, Agnieszka Radwanska, Caroline Wozniacki, Angelique Kerber, Ekaterina Makarova, Dominika Cibulkova and Flavia Pennetta the Top 8 seeds, and another six Top 20 players among the unseeded contingent - namely Andrea Petkovic, Sara Errani, Lucie Safarova, Carla Suárez Navarro, Alizé Cornet and Garbiñe Muguruza.

3) Halep is trying to become the first two-time WTA title winner of the year.
Halep was one of three WTA title winners in Week 1 of the 2015 season, winning in Shenzhen. Maria Sharapova won Brisbane and Venus Williams won Auckland, but neither is playing in Week 2.

4) Kvitova is looking to rebound from a semifinal loss in Shenzhen.
Kvitova fell to World No.47 Timea Bacsinszky in the semifinals of Shenzhen last week, but she has always done well in Sydney - she's made the semis in two of three tries here, in 2012 and 2014.

5) Radwanska is playing her first WTA event of 2015, but...
Radwanska, a former Sydney champion, is playing her first WTA event of the year, but she shone brightly at the Hopman Cup exhibition event last week, going 2-1 in the round robin portion (the one loss coming against Cornet) and then beating Serena Williams in the final (read more here).

6) Home favorite, Hobart favorite.
Australia's own Casey Dellacqua is the No.1 seed in Hobart. The other seeds are Zarina Diyas, Camila Giorgi, Sloane Stephens, Klara Koukalova, Mona Barthel, Alison Riske and Roberta Vinci.

7) Dellacqua is the No.1 seed at a WTA event for the first time.
Not only is Dellacqua the top seed at a WTA event for the first time, but she's only ever been seeded in the Top 10 at a WTA event once before - she was the No.2 seed at Pattaya City in 2008.

8) The doubles draws are packed this week.
Three of the very best doubles teams in the world are in Sydney, namely Raquel Kops-Jones and Abigail Spears, Martina Hingis and Flavia Pennetta and Muguruza and Suárez Navarro, the Top 3 seeds there. Hobart has two doubles legends too - former World No.1s Cara Black and Lisa Raymond are there, playing with other partners (Black with Zheng Saisai and Raymond Mirjana Lucic-Baroni).

9) The Australian Open doesn't start until next week, but the excitement starts this week.
Main draw play at the Australian Open starts a week from Monday, but over the next week there's a lot going on at the Happy Slam - Monday's rankings will determine the seedings, the qualifying draw takes place throughout the week, and the main draw ceremony will take place on Friday.
