On 1 August 2022, Scarlett and Sofia's business, Clipped Wings, operating in Parramatta, NSW, have entered into a contract with Henny Chicken to give her and her bridesmaid a special haircut for her wedding. The parties agree to the following terms:

Price $2,000, Perm and colouring,

For the bride and her bridesmaid Amanda,

The hair styling must start at 6 am and finish by 11am on Sat, 20 Aug 2022, and

Payment to be made at the conclusion of the hair styling.

They arrive just before 6:00am at the home of the bride and set up and are about to start work on the ladies hair when the electricity power is cut-off.

They investigate the source and telephone the Electricity provider who explains the power will not come on until 11am.

Scarlett and Sofia offer to cut and style without a perm for $1000 as this does not require electricity. Henny Chicken agrees.

The hairstyling is done and Scarlett & Sofia demand payment of $1000.

The bride, Henny Chicken, says "no, you breached our original contract, so you owe me $1,000, that is the $2000 less the $1000 for this lesser hair cut".

Scarlett and Sofia are angry and leave without either party paying.

a) Advise Scarlett and Sofia as what rights and obligations they may have to Henny Chicken.

b) Would your answer be different if Scarlett mentions to you that Henny Chicken is in fact her younger sister?
