grammatical number - 'is' or 'are' in lists of counted nouns

Which of the following is correct?
Does the is/are depend on the total number of things in the list, or only on the thing immediately following the is/are?

There is 1 apple and 1 orange available.
There are 1 apple and 1 orange available.

Also, would it make a difference if one would put the is/are near the end, like so?

1 apple and 1 orange is available.
1 apple and 1 orange are available.

Answer

This one is right:

There is 1 apple and 1 orange available

This is wrong:

There are 1 apple and 1 orange available.

I would personally say

There is an apple and an orange available.

This is now wrong

1 apple and 1 orange is available

This is right (almost):

1 apple and 1 orange are available.

But again, I would say

An apple and an orange are available.

These are both correct:

There is an apple and 2 oranges available.
There are 2 apples and an orange available

So it depends on the number of objects the is/are is referring to first.

2 apples and an orange are available.
An apples and 2 oranges are available.

When it is at the end, it refers to the total number of objects.
