To simplify the expression

\[
\left( \frac{x^{-5} y}{z} \right)^{-6},
\]

we will use the rules of exponents. Specifically, we will use the property that \((a/b)^{-n} = \frac{b^n}{a^n}\) and the property that \((a^m)^n = a^{m \cdot n}\).

First, we apply the negative exponent rule:

\[
\left( \frac{x^{-5} y}{z} \right)^{-6} = \frac{z^6}{(x^{-5} y)^6}.
\]

Next, we'll simplify the denominator \((x^{-5} y)^6\):

\[
(x^{-5} y)^6 = (x^{-5})^6 \cdot (y^6) = x^{-30} y^6.
\]

Now we can rewrite the entire expression:

\[
\frac{z^6}{x^{-30} y^6}.
\]

To handle the negative exponent in the denominator, we can rewrite it as:

\[
\frac{z^6}{x^{-30} y^6} = z^6 \cdot \frac{1}{x^{-30} y^6} = z^6 \cdot \frac{1}{y^6} \cdot x^{30}.
\]

This can be expressed as:

\[
z^6 \cdot x^{30} \cdot \frac{1}{y^6} = \frac{x^{30} z^6}{y^6}.
\]

Thus, the simplified expression is:

\[
\frac{x^{30} z^6}{y^6}.
\]

Therefore, the final answer is:

\[
\frac{x^{30} z^6}{y^6}.
\]
