Given this paragraph on Macquarie University Real Tennis Club, please tell me how many tennis courts the club had.

The Macquarie University Real Tennis Club (formerly the Sydney Real Tennis Club) played real tennis at Macquarie University in Sydney, Australia. Its only court closed on 31 December 2005, converted to other athletic uses. However, the university has agreed to provide land for another court as well as A$350,000 toward its construction. The club is working to provide additional funds required to begin construction.

Based on this paragraph, it appears that the Macquarie University Real Tennis Club had only one tennis court.
