I found a site with some studies:
The Linus Pauling Institute
A number of studies have compared tea tree oil with conventional medications:

* The topical application of 5% tea tree oil versus 5% benzoyl peroxide has been investigated in the treatment of acne vulgaris caused by the microorganism Propionibacterium acnes. Both compounds reduced the number of acne lesions, although the action of tea tree oil was slower, possibly due to the use of a suboptimal concentration. Tea tree oil produced fewer side effects than the benzoyl peroxide.

* The use of 10% tea tree oil cream has been compared with 1% tolnaflate and placebo creams in the treatment of tinea pedis, or ringworm. This is the commonest form of superficial dermal infection caused by several related fungi. Patients in the tea tree group and tolnaflate group had significant clinical improvement, but the tea tree oil did not cure the condition. However, as with the acne study, the concentration of the oil may have been suboptimal. Unlike the oil, tolnaflate use resulted in minor skin irritation.

* In another study, the topical application of 1% clotrimazole solution or 100% tea tree oil for the treatment of toenail disease (onychomycosis) resulted in nearly identical clinical improvement.

* Gynecological conditions, including vaginal infections like trichomonal vaginitis, have been successfully treated with tea tree oil. Anaerobic (bacterial) vaginosis is usually treated with oral nitroimidazoles like metronidazole, but these drugs may cause toxic side effects, and long-term recurrence is very high. Topical treatment with tea tree oil may be more effective because the abnormal bacterial flora is replaced by normal lactobacillus.
