Nigel Westlake (born 6 September 1958) is an Australian composer, performer and conductor.

Nigel Westlake's career in music has spanned more than 3 decades. He studied the clarinet with his father, Donald Westlake (principal clarinettist, Sydney Symphony Orchestra 1961-1979) and subsequently left school early to pursue a performance career in music. Nigel toured Australia and the world playing with ballet companies, a circus troupe, chamber music groups, fusion bands and orchestras to the cities of London, New York, Rome, Washington, Tokyo, Beijing, Paris, Amsterdam, Vancouver, Moscow, Hong Kong, Berlin, New Delhi and Singapore and many others.

His interest in composition dates from the late 1970s when he formed a classical/jazz-rock/world-music fusion band to play original music. During this time he started to receive offers to compose for radio and circus. Commissions for TV and film soon followed. In 1983 he furthered his studies of contemporary music in the Netherlands. From 1987 to 1992 he was a clarinettist with the Australia Ensemble resident at the University of New South Wales. In 1992 he joined guitarist John Williams's group 'Attacca' as a performer and composer for tours of the United Kingdom and Australia. Since then he has given his primary attention to composition.

The Sydney Symphony Orchestra (abbreviation – SSO), commonly known as the Sydney Symphony, is an Australian symphony orchestra based in Sydney. It has the unique privilege of having the Sydney Opera House as its home concert hall. The orchestra's current chief conductor is Vladimir Ashkenazy. His term will conclude in 2013, and David Robertson will succeed him from 2014.

The Sydney Symphony is an icon of the Sydney cultural scene, performing around 150 concerts a year to a combined annual audience of more than 350,000. The regular subscription concert series are mostly performed at the Sydney Opera House but other venues around Sydney are used as well, including the City Recital Hall at Angel Place and the Sydney Town Hall. The Town Hall was the home of the orchestra until the opening of the Opera House in 1973. Since then, most concerts have been taking place in the Opera House's Concert Hall (capacity: 2,679 seats).

A major annual event for the orchestra is Symphony in the Domain, a free evening outdoor picnic concert held in the summer month of January in the large city park known as The Domain. This event draws audiences of over 80,000 and is a long-established part of the Sydney summer cultural calendar.
