Blish - one thing I could not find out was without clergy do they actually have services as such or can you just rock up to the temple and pray/contemplate etc as you will! I was unable to find out anything about it on the website!
Yep - feel free to "rock up"

The Baha'i temples are open to the public. They are there for anyone to come in and pray, meditate, contemplate. I do believe the Baha'i Community in Mona Vale (where the temple is) do conduct a service on the weekend which includes a choir and readings from the Writings of Baha'u'llah and other Faiths.
Actually, just found this on the Australian Baha'i website:
QUOTE
The Australian Baha'i Temple, or House of Worship, is a place of prayer and meditation that is open to people of all beliefs.
We offer the Temple as a gift to the Australian people in line with our belief in the oneness of God, the oneness of His Messengers and the oneness of humanity.
Located in the beautiful hills and bushland above the northern beaches of Sydney, it is one of seven Baha’i Temples throughout the world.
Other Baha’i Temples are located in Apia, Samoa; Chicago, USA; Frankfurt, Germany; Kampala, Uganda; New Delhi, India; and Panama City, Panama. A new Baha’i Temple is being built in Santiago, Chile.
Each Temple is designed to be distinctive, the unifying factor being that all are nine-sided – a symbol of the unity of the world religions.
Like all Baha’i Temples, the Australian Temple is intended to become a future hub for social, scientific, educational and humanitarian services.
We invite you to visit the Temple, which is open to the public from 9 am to 5 pm every day of the year, and to 7 pm in summer months. A public service is held every Sunday at 11 am.
Oh, and don't feel scared of going - Baha'is are forbidden to prozelytise (to ear bash you). If you ask questions, obviously we can answer; but we are not trying to convert you...one of the fundamental teachings of the Faith is "independent investigation of truth", meaning one should study and find what's true for themselves rather than blindly follow what others say.
Found this about the temple service:

Worship Services
A public devotional service is held every Sunday beginning at 11 am.
The 40-minute service includes readings from the sacred writings of the major religions of the world, and acapella performances by the Baha'i Temple Choir.
No sermons or talks are given inside the Temple. Ordinary members of the community - men and women, adults and children - read the texts without commentary.
There are no collections during the service. Only Baha'is may donate funds for the upkeep of the Temple.
Special services of worship are held from time to time to commemorate Baha'i Holy Days, special United Nations days such as International Women's Day, International Day of Peace and Human Rights Day, and other important events, such as National Refugee Week.
An invited speaker gives a talk in the Information Centre following most special services. All are welcome to attend.
