Gene
A hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism. Genes undergo mutation when their DNA sequence changes.
Allele
One member of a pair or series of genes that occupy a specific position on a specific chromosome.
Hope that was helpful.

well from hsc online, it says:
distinguish between the terms allele and gene, using examples
An allele is an alternative for a particular inheritable characteristic, e.g. tall (T) and short (t) are two alleles for the characteristic of height in some plants. In humans, straight (S) and widow's peak (s) are two alleles for hairline. With the development of modern genetics, we now identify these factors as genes. A gene is a section of DNA coding for proteins that expresses itself as the phenotype of an organism. Alleles are alternative forms of a gene. In many sources you will find the terms allele and gene used to mean the same thing.
u can go to http://hsc.csu.edu.au/biology/core/blueprint
its heaps helpful, since it outlines all of the syllabus dot points in biology and most other subjects. i'm using it to since i hav my 1/2 yearly exams next week, with bio in 9 days!!!

Thought I'd share a neat little analogy I recently found for the two.
A gene is like your livingroom.
You can decorate your livingroom in retro or contemporary, but you still have a livingroom.
In genetics, everyone has a gene for eye color (simplification). You could have the allele for blue eyes or the allele for brown eyes.
There are different alleles for every gene, like there are different ways to decorate your livingroom.
I thought it was really neat, though it probably won't make much sense to someone living in a studio all their life.

PS, DrDoom states:
Gene: Is the height
Allele: How high or short the person actually is.
In that example the gene in consideration is that which codes for height. One allele (form of the gene) for height makes you tall, and the other allele (form of the gene) for height makes you short. How high or short the person actually is is their phenotype, or the physical expression of the allele. No flame, just clarification.
